Which free plan fits how you send?
- You send a few dozen personal emails most days: a daily cap matters more than a monthly one. BetterMerge (50 a day) and Mailmeteor (about 50 a day, 500 a month) fit best.
- You need to know who opened: BetterMerge, Mailmeteor, and Mergo all include open and click tracking for free. YAMM limits free sending to 20 a day.
- You send one big announcement: Mergo's first campaign has no recipient cap. After that it is 30 per campaign.
- You already pay for Google Workspace: try Gmail's built-in mail merge first. Move to an add-on when you need tracking, attachments per person, or scheduling.
BetterMerge free plan
50 emails a day from your own Gmail or Google Workspace account, up to 5 campaigns a month, open and click tracking, personalized subject lines and bodies, and an unsubscribe link in every email. You can use both the Google Sheets add-on and the web app. Scheduling, attachments, and follow-ups by engagement start on the Lite plan. Seeall plans.
YAMM free limit
Yet Another Mail Merge sends 20 emails a day on its free plan, on Gmail and Workspace accounts alike. That is enough to test the add-on but tight for regular outreach. Paid YAMM plans go to 400 a day for Gmail accounts and 1,500 a day for Workspace. Compare BetterMerge and YAMM.
Mailmeteor free plan limits
Mailmeteor's Hobby plan allows 500 emails a month. If you send 50 a day, you run out in about ten days. Tracking is included on the free plan, which is a real advantage. Compare BetterMerge and Mailmeteor.
Mergo free plan
Mergo lets your first campaign go to any number of recipients, then limits free campaigns to 30 emails each. It suits people who send one large campaign and then small ones. Compare BetterMerge and Mergo.
Does GMass have a free plan?
No. GMass offers a free trial, not a permanent free plan, and paid plans cost noticeably more than the Sheets add-ons. It is built for high-volume cold email. Compare BetterMerge and GMass.
Gmail's built-in mail merge
Eligible Google Workspace editions include a native mail merge that sends up to 1,500 recipients a day. Merge tags only work in the email body, there is no open or click tracking, and it cannot be scheduled. It is not available on free @gmail.com accounts. Read more in our Gmail mail merge guide.
