The Best GMass Alternative for Teams Ready to Go Beyond Mail Merge

GMass turns Gmail into a mass email tool. Supapitch turns your outreach into a conversation — with AI that researches, writes, and adapts every email to each recipient.

Why Teams Leave GMass

GMass is mail merge for Gmail at $19.95/mo — connect a Google Sheet, write a template, and blast it to your list. It works for newsletters, but teams hit walls when they need real outreach performance.

Personalization is limited to merge tags — every recipient gets the same email with different fill-in-the-blank values

Gmail-only — no Outlook, no custom SMTP, no multi-provider team accounts

Gmail's daily sending limits become a hard bottleneck GMass can't solve
