GMass's "unlimited" sending requires external SMTP configuration or their ColdSMTP service, which may carry additional costs. GMass also offers reduced regional pricing in some countries; figures above are USD list price.

Why BetterMerge fits most senders better

About 50% cheaper at the top tier

Pro is $299.90/year against GMass Professional's $599/year — roughly $299 less per year. BetterMerge also has a free plan (50/day); GMass is trial-only.

No Chrome extension to manage

GMass runs as a Chrome extension inside Gmail. BetterMerge is a Google Sheets add-on plus a standalone web dashboard — nothing to install in the browser.

Built for the send, not the funnel

GMass packs in spintax, A/B testing, CRM tools, and a full cold-outreach stack. BetterMerge sticks to personalization, tracking, scheduling, and contact management — the parts most senders actually use.

Sending within Gmail's own limits

BetterMerge caps out at Gmail's own ceilings (2,000/day on Workspace), which keeps your account in Google's good graces for newsletters and customer email.

Where GMass still wins

If you need to send past Gmail's daily limits entirely, GMass's ColdSMTP and MultiSend routing get you there — BetterMerge doesn't try to. GMass also ships email warm-up, spam solver, spintax, REST API and webhooks, and a built-in CRM, none of which BetterMerge offers today. For aggressive cold-outreach at scale, GMass is the more complete tool.
