MergelineMergeline
Best if you want 60 free emails a day, follow-ups that stop on reply for $99 a year, and lists that never leave your browser. It sends at a human pace up to Gmail’s own limit, so it is not built for thousands of emails a day.
Best Right Inbox alternatives for Gmail mail merge
The best Right Inbox alternatives for Gmail mail merge in 2026 are Mergeline, GMass, Mailmeteor and Streak. Right Inbox’s free plan does not include mail merge, so you pay from the first send. Mergeline includes mail merge free for 60 emails a day and adds up to 7 follow-ups that stop on reply on Pro.
What does Right Inbox do well?
- A bundle of Gmail tools, with mail merge, sequences and email tracking in one paid plan1.
- A low price: Professional at $9.95 a month, or $7.95 a month billed yearly1.
- It works as a browser extension in Chrome, Safari and Firefox1.
- It lets you set a daily send rate for mail merge2.
- A Team plan at $19.95 per user a month, or $16.95 billed yearly1.
Why do people look for a Right Inbox alternative?
Right Inbox’s free “Limited” plan leaves out mail merge, tracking and sequences, and limits several features to 5 emails a month1. If mail merge is the only thing you need, you pay for a bundle of other Gmail tools to get it.
The feature page does not state a daily mail merge cap; it lets you set a daily send rate instead2. Its privacy policy and permission list were not part of our research, so check them on its site before you decide. Plans are priced per user, so a team of five pays for five seats.
If what you want is “email these 80 people, then follow up with the ones who did not answer”, a dedicated mail merge tool with a free tier may be enough. People asking for exactly that on Reddit describe the rule simply: “The sequence should stop if the person responds.”3
