Verified GMass Discount Codes & Promo Code For Jun 2026

Best GMass Offers Available on GrabOn

Six live promotions sit on the GMass page right now, all editor-verified. The deepest single line is the annual-billing route, which cuts the effective monthly rate roughly 30 percent below month-to-month pricing across all three individual tiers. The standout feature on the platform is the dedicated cold email sending server tier, which routes email through a separate IP infrastructure rather than running purely through Gmail's standard sending limits; this matters for India B2B sales teams running outbound campaigns above the standard 500-send daily Gmail ceiling.

The annual billing route is the cleanest single saving for any sustained user; the Standard tier drops from $29.95 monthly to $20.75 monthly when paid annually, a 31 percent cut on the same feature set. The Premium tier is the right pick for marketers who need A/B testing, advanced click tracking, multi-stage conditional sequences, and API access without paying the Professional premium. The Professional tier unlocks MultiSend for inbox rotation (sending across multiple Gmail accounts to spread volume), the dedicated cold email sending server, plus priority support and access to any upcoming pro features. The free plan caps at 50 emails per day, which is the right route to test the workflow before paying.

About GMass and Gmail Mail Merge

GMass is a Gmail-integrated mail merge and cold email SaaS plugin. It installs as a Chrome extension on Gmail, then layers mass-send, automation, follow-up, tracking, and AI-template features on top of the standard Gmail compose interface. The product targets three buyer segments: solo marketers and freelancers running newsletter and outreach campaigns, B2B sales teams running cold email prospecting, and agencies managing email campaigns for client accounts. The brand has been around since the early 2010s and has gone through several pricing and feature evolutions, with the most recent change effective January 1, 2026, raising prices to reflect newer capabilities including the dedicated cold email server, AI HTML template builder, unlimited follow-ups, and AI spintax.

The platform competes against a layered email marketing and cold email category: Mailchimp (the broad email marketing platform with newsletter focus), HubSpot (the CRM-plus-email suite at the enterprise tier), Salesforce Marketing Cloud (the enterprise-only route), ConvertKit and Substack (the creator-and-newsletter angle), Klaviyo (e-commerce-specific email), Yet Another Mail Merge or YAMM (the direct Gmail mail merge competitor), Mixmax (Gmail sales productivity), Apollo and Lemlist (the cold email specialists), Outreach and SalesLoft (the enterprise sales engagement platforms), and Reply.io (the multi-channel outbound suite). GMass's wedge is the Gmail-native integration without leaving the Gmail interface, paired with the cold email server access at the Professional tier that pushes beyond Gmail's standard daily limits.

The Gmail daily send limits matter here. A standard Gmail account allows up to 500 emails per day on personal Gmail and up to 2,000 emails per day on Google Workspace Business accounts. GMass installed against a standard account still respects these limits at the Gmail level, but the Professional tier's dedicated cold email server routes through a separate sending infrastructure, which lets users push higher volumes without hitting the Gmail ceiling. This is the practical reason B2B sales teams running aggressive outbound prospecting (200-plus warm contacts per day) upgrade from Standard to Professional.

For India buyers, the practical GMass use cases sit in four lanes. First, freelance and small-business newsletter sending where the Standard tier handles the 100 to 500 daily contact volume. Second, B2B sales teams running cold email prospecting where the Professional tier with cold email server access and MultiSend inbox rotation supports higher daily volume. Third, agencies managing client email campaigns where the Team plan multi-seat pricing covers shared account access. Fourth, ecommerce teams running customer retention email where Klaviyo's depth on transactional flows may suit better but GMass's simplicity wins for one-off campaign sends.

Plan Breakdown: Standard, Premium, Professional, Team

Standard Plan: $29.95 Monthly or $20.75 Annual

The entry tier. Standard covers the core GMass functions: mail merge against a Google Sheets contact list, basic follow-up automation, link tracking, open tracking, and the standard Gmail-limit send volume. The annual route at $20.75 per month (paid as $249 once a year) cuts the effective rate 31 percent below the monthly $29.95. This is the right tier for solo freelancers, content creators, small-business owners, and newsletter senders running 50 to 500 daily emails. The follow-up automation supports up to a defined number of follow-up stages per campaign on this tier.

Premium Plan: $39.95 Monthly

The mid tier. Premium adds A/B testing (testing subject lines, send times, and email body variants against each other), advanced click tracking analytics (per-link click maps and per-recipient click history), multi-stage conditional sequences (branching follow-ups based on whether the recipient opened or clicked), and API access (for tying GMass to external automation tools like Zapier, Make, or in-house workflow apps). This is the right tier for marketers who want the analytics depth to run actual data-driven campaign optimisation, plus the API to connect GMass to other tools in the stack.

Professional Plan: $59.95 Monthly or $49.92 Annual

The top individual tier. Professional adds MultiSend for inbox rotation (sending the same campaign across multiple connected Gmail accounts to distribute volume and avoid single-account limit caps), the dedicated cold email sending server (routing through a separate IP infrastructure to push higher daily volumes), unlimited follow-up stages, the AI HTML template builder (generates email templates from prompt input), AI spintax (rotating word variants to make each email slightly different and reduce spam-filter pattern detection), and priority support. The annual route at $49.92 per month (paid as $599 once a year) cuts the effective rate 17 percent below the monthly $59.95. This is the cold email specialist tier for B2B sales teams running aggressive outbound prospecting.

Team Plans

The multi-seat tier. Team plans inherit the full Professional tier feature set across all seats, with multi-seat admin (one admin manages multiple sender accounts), team-level reporting, and shared template libraries. Pricing scales by seat count; the annual route applies the same percentage saving as the individual tiers. This is the right tier for digital marketing agencies managing client email campaigns, B2B sales organisations with multiple SDRs (sales development representatives), and any team where two or more people send email campaigns from separate Gmail accounts under one organisation.

Free Tier (50 Emails Per Day)

The evaluation route. The free GMass tier caps at 50 emails per day and includes the core mail merge function with a basic feature scope (no A/B testing, no AI templates, no dedicated server, no MultiSend). This is the right path to test the workflow before paying, to validate whether GMass fits the Gmail-native compose flow you prefer, and to compare against the free tiers of YAMM and Mixmax before committing. Once you cross the 50-email daily volume threshold or need any advanced feature, the Standard tier annual route is the cheapest upgrade.

How to Apply a GMass Coupon

1. Open the GMass coupons page on GrabOn and pick the offer matching your plan choice (the sitewide promo code for any tier upgrade, the annual route for the deepest saving on Standard or Professional, or the team plan code for multi-seat agency setups).
2. Copy the code from the coupon box, then tap Activate Offer. A new tab opens at gmass.co with the routing applied.
3. On gmass.co, open the Pricing page. Pick your plan tier (Standard, Premium, Professional, or Team) and billing cycle (monthly or annual).
4. On the checkout page, find the "Discount code" or "Promo code" field below the plan selection. Paste the code and tap Apply. The discount appears in the order summary.
5. Complete payment via Visa, Mastercard, American Express, or PayPal. International cards work for the USD billing if you are an Indian buyer. The GMass Chrome extension is automatically activated against your Gmail account once payment confirms.

The discount applies before payment confirmation. Promo codes typically discount the first billing cycle only; subsequent renewals revert to the standard rate at the plan tier and billing cycle you selected. For sustained users on annual plans, the annual saving (31 percent on Standard, 17 percent on Professional) is permanent across the prepaid year.

More Ways to Save at GMass

• Switch from monthly to annual billing once you have validated 3-plus months of sustained use. The 31 percent annual saving on Standard and the 17 percent saving on Professional compound across the prepaid year and the saving is locked in for the full term.
• Start on the free 50-email-per-day tier to test the workflow against your Gmail account before paying. Validate that the Chrome extension installs cleanly, the Google Sheets connection works for your contact list format, and the follow-up automation behaves the way you expect.
• Use a zero-forex credit card for the USD billing. Indian cards like Niyo Global, Federal Bank Scapia, and IDFC First Wow waive the 3 to 3.5 percent forex markup. On the $599 annual Professional plan, the forex saving is roughly Rs 1,500 to Rs 1,800 across the year.
• Claim the OIDAR GST input tax credit if you are a registered business with a GSTIN. GMass charges 18 percent IGST on the billed amount as an Online Information and Database Access or Retrieval service. Indian businesses can claim this 18 percent as input credit against output GST liability, which effectively zeroes the GST cost for registered B2B buyers.
• Stack the GrabOn sitewide promo code on top of the annual route during launch and seasonal campaign windows. The percentage code typically applies to the first billing cycle, which means picking annual at the discount window locks the lower effective rate for 12 months.
• Cross-check GMass against YAMM (Yet Another Mail Merge) and Mixmax before committing on the Professional tier. For low-volume users (under 100 emails per day), YAMM's lower price tier may be sufficient; for sales-team workflows, Mixmax's Salesforce integration may justify the higher Mixmax cost. GMass is the value pick for the volume between these two.
• For agencies, evaluate the Team plan against multiple individual Professional tiers. Team plans inherit the Professional features across all seats with shared admin, and the multi-seat pricing typically beats the standalone-sum of equivalent individual Professional accounts at 3-plus seats.

Coupon Not Working? Common Fixes

• Promo code says "invalid": Codes are campaign-specific and time-limited. Refresh the GrabOn GMass page and pick a currently-active code; expired codes are pulled within a day.
• Code applies on monthly but not on annual: Some codes are billing-cycle-specific. Toggle between monthly and annual on the Pricing page to see which the code accepts. For sustained users, the annual route plus a code applicable to annual is the cleanest stack.
• Code applies on Standard but not on Professional: Some codes scope to specific tiers. Toggle plan tiers on the Pricing page to confirm scope, or pick a code that applies sitewide to all tiers.
• Discount looks smaller in cart than expected: The percentage applies to the plan subscription portion only, not to taxes or fees added at checkout. The pre-tax line is the actual saving comparison.
• Indian credit card declined: Most premium Indian credit cards (HDFC, Axis, ICICI, SBI premium tiers) support recurring international subscriptions. Add gmass.co to the approved international merchant list in your card app, or contact your bank to enable international transactions.
• "Currency conversion failed" error: Switch to PayPal or an alternative international card. Indian credit cards generally support USD billing; debit cards have variable support and may need to be enabled for international use at your bank.
• Chrome extension not connecting to Gmail: Ensure you are logged into the correct Gmail account that matches your GMass subscription. The extension binds to the Gmail account it is activated against; switching Gmail accounts mid-session can break the connection until you re-authenticate.
• Daily Gmail send limit hit before campaign completes: Standard Gmail caps at 500 emails per day, Google Workspace Business at 2,000. If your campaign size exceeds the cap, upgrade to Professional for MultiSend inbox rotation and the dedicated cold email sending server, or split the campaign across multiple days.

India Buyer Guide: Forex, OIDAR GST, Gmail Limits

GMass is a US-headquartered Gmail mail merge SaaS billing in USD. India buyers face three cost layers beyond the published USD rate. The first is the forex markup, Indian credit cards charge a 3 to 3.5 percent international transaction fee on top of the conversion rate, which adds roughly Rs 60 to Rs 80 on a $29.95 monthly invoice and roughly Rs 1,500 to Rs 1,800 on a $599 annual prepay. Zero-forex cards (Niyo Global, Federal Bank Scapia, IDFC First Wow Visa Infinite) waive this markup, which is the cleanest route for any sustained USD subscription.

The second cost layer is OIDAR GST. Online Information and Database Access or Retrieval services purchased by Indian users are subject to 18 percent IGST under the GST Act. For B2C buyers (individual freelancers paying for personal use), the GST is collected by GMass and remitted to the Indian government, and the effective cost runs 18 percent above the headline USD figure. For B2B buyers (companies with a registered GSTIN), the buyer can claim the 18 percent as input tax credit against the company's output GST liability, which effectively zeroes the GST cost for registered businesses. Always provide the company GSTIN at checkout to enable the input credit path.

The third practical consideration is the Gmail daily send limit. Standard Gmail (free personal accounts) caps at 500 emails per day, while Google Workspace Business accounts allow up to 2,000 emails per day. GMass installed against a standard Gmail account still respects these Gmail-level caps even on the Professional tier, but the Professional tier's dedicated cold email server routes through a separate sending infrastructure for the high-volume push beyond the Gmail ceiling. For Indian B2B sales teams running aggressive outbound prospecting (200-plus daily contacts per SDR), upgrading to Professional plus the cold email server is the practical bottleneck removal.

The fourth softer consideration is data residency. GMass servers are US-hosted, which means email metadata (campaign content, recipient lists, tracking data) is stored on US infrastructure. For India enterprises with strict data residency policies under the Digital Personal Data Protection Act (DPDP) framework, the data flow needs to be reviewed by the company's legal and compliance team before deployment. For most small businesses, freelancers, and standard B2B teams, this is not a practical concern since the underlying Gmail data already sits on Google's US-and-global infrastructure.

The Verdict: Who Should Subscribe

Best for: India freelancers and small business owners running newsletter or outreach campaigns at 50 to 500 daily emails (Standard tier annual route). India marketers wanting A/B testing, click tracking, and API access for data-driven campaign work (Premium tier). India B2B sales teams running cold email prospecting above standard Gmail limits (Professional tier with cold email server and MultiSend). India digital marketing agencies managing client email campaigns across multiple sender accounts (Team plans).

Be careful if: Your daily email volume sits under 50 emails per day, where the free tier may be sufficient and the paid tiers are excess capacity. If you are running e-commerce transactional and lifecycle email (welcome series, abandoned cart, post-purchase), Klaviyo's depth on these flows likely justifies the higher cost over GMass's campaign-focus. If your team needs deep Salesforce or HubSpot CRM integration with email as one component, Mixmax or the CRM-native email modules may suit better than GMass's Gmail-only scope.

Best saving move: Start on the free 50-email-per-day tier to validate the workflow against your Gmail account, then upgrade to the Standard or Professional annual route once usage stabilises. Pay via a zero-forex card (Niyo Global, Federal Bank Scapia, or IDFC First Wow), claim the OIDAR GST input credit if you are a registered business with a GSTIN, and apply the GrabOn sitewide promo code at checkout to compound the saving on the first billing cycle. The combined stack brings the effective annual cost roughly 35 to 45 percent below the published monthly rate for a B2B India buyer.

GMass FAQs

How much does GMass cost per month?

GMass plans start at $29.95 per month on the Standard monthly tier, $39.95 per month on Premium, and $59.95 per month on Professional. Annual billing cuts the effective monthly rate roughly 31 percent on Standard (to $20.75 per month, paid as $249 annually) and 17 percent on Professional (to $49.92 per month, paid as $599 annually). A free tier capped at 50 emails per day is available for evaluation. Team plans are available with multi-seat pricing.

Does GMass work with Indian Gmail accounts?

Yes, GMass works with any Gmail account including standard personal Gmail and Google Workspace Business accounts in India. The product installs as a Chrome extension on the Gmail compose interface and integrates with your existing Gmail account without changing email sending mechanics. Most premium Indian credit cards (HDFC, Axis, ICICI, SBI premium tiers) support the USD billing for the subscription. India buyers also have access to the OIDAR GST input credit if the account is registered as a B2B business with a GSTIN.

What is the difference between GMass Standard and Professional?

Standard covers core mail merge, basic follow-up automation, link and open tracking, plus standard Gmail send volume. Professional adds MultiSend for inbox rotation (sending across multiple Gmail accounts to distribute volume), the dedicated cold email sending server (separate IP infrastructure beyond Gmail's standard limits), unlimited follow-up stages, the AI HTML template builder, AI spintax, and priority support. Professional is the right tier for B2B sales teams running cold email prospecting above 200 daily contacts per sender.

Can I cancel my GMass subscription anytime?

Yes, monthly GMass subscriptions can be cancelled anytime from the account settings page with no further charges from the next billing cycle. Annual prepaid plans cancel at the end of the prepaid term; pro-rated refunds may be available in specific cases per the refund policy. Account access continues until the end of the paid period regardless of cancellation timing. After cancellation, the Chrome extension reverts to the free 50-email-per-day tier or is disabled depending on account status.

Does GMass charge GST for India users?

Yes, GMass charges 18 percent IGST on subscriptions for Indian users as an Online Information and Database Access or Retrieval (OIDAR) service. For B2C buyers (individuals), the GST is added to the invoice and remitted to the Indian government. For B2B buyers (registered businesses with a GSTIN), the GST can be claimed as input tax credit against the company's output GST liability. Provide the company GSTIN at checkout to enable input credit tracking, which effectively zeroes the GST cost for registered B2B India buyers.

What are the Gmail send limits when using GMass?

Standard personal Gmail accounts cap at 500 emails per day, and Google Workspace Business accounts cap at 2,000 emails per day. GMass installed against a standard Gmail account still respects these Gmail-level caps. To exceed these limits, the GMass Professional tier offers MultiSend for sending across multiple connected Gmail accounts and the dedicated cold email sending server for routing through separate IP infrastructure. For sustained B2B prospecting above 200 daily contacts per sender, the Professional tier is the practical bottleneck removal.

How does GMass compare to YAMM and Mixmax?

YAMM (Yet Another Mail Merge) is the direct Gmail mail merge competitor at a lower price tier; it suits low-volume users under 100 emails per day. Mixmax is a Gmail sales productivity tool with deeper Salesforce integration at a higher price point; it suits sales teams with CRM-tight workflows. GMass sits between the two, with Gmail-native integration like YAMM, plus the cold email server and MultiSend depth that competes against the dedicated cold email tools like Lemlist and Apollo. For most Indian solo marketers and B2B sales teams, GMass is the value pick.

What is the deepest current GMass discount?

The deepest layered saving combines the annual billing route (31 percent below monthly on Standard, 17 percent on Professional) with the GrabOn sitewide promo code applied to the first billing cycle. For India buyers, paying via a zero-forex card (Niyo Global, Federal Bank Scapia, or IDFC First Wow) and claiming the OIDAR GST input credit as a registered business adds another 18 to 22 percent saving. The combined stack brings the effective annual cost roughly 35 to 45 percent below the published monthly rate.
