Our take

Is Mergo worth buying?

Based on the StackSocial listing, this is a lifetime Google add-on for mail merges from Gmail, with tracking and follow-ups. A buyer review mentions a daily cap that the listing does not confirm. It suits small senders who live in Google Workspace.

Why Mergo

Mail merges from Gmail normally need a separate sending service or manual copying. Mergo runs inside Google tools you already use. One buyer review mentions a 500 emails per day cap, but the listing does not confirm it, so check Google's own sending limits.
