YAMM review (2026): pricing, limits, pros and cons

What YAMM is

YAMM, Yet Another Mail Merge, is a Google Sheets add-on that sends personalised emails through your own Gmail or Google Workspace account. You write a draft in Gmail with placeholders, point YAMM at a sheet of recipients, and it sends one email per row, tracks opens, clicks, responses, bounces and unsubscribes back into the sheet, and schedules or follows up. It has been around since 2014, is made by Talarian in Luxembourg, and ranks among the most installed Workspace add-ons. It is not a cold email tool, and this page exists because people searching for it often wonder whether it could be.

YAMM pricing

Plans are per Google account and billed yearly. The free plan sends to 20 recipients a day with open, click and response tracking, unsubscribe and bounce tracking and no branded footer. Pro for a gmail.com account is $3 a month, $36 billed annually, for 400 recipients a day and adds scheduling and priority support. Pro for a Google Workspace account is $6 a month, $72 billed annually, for 1,500 recipients a day, and the page is careful about that number: it applies to a paid, non-trial Workspace account that has not sent more than 500 emails in the last 24 hours and has not been rate-limited by Google. Team is $6 a user a month on a Workspace domain, so 5 accounts cost $30 a month or $360 billed annually, with 1,500 a day per user; above 100 users YAMM quotes a custom price. Prices vary by billing country and exclude tax.

The terms are strict but plainly stated. Licences renew automatically with a reminder, cancellation takes effect at the end of the term with no prorated refund, and refunds are given only in extraordinary circumstances and never on subscriptions older than 90 days.

What it does

The feature list is deep for the price: Gmail Layouts and HTML templates, personalised subject lines, links, images and attachments, sending from an alias, personalised CC and BCC, scheduling, follow-up campaigns in the same thread, filtered follow-ups, one-click surveys, Google Forms notifications, and automatic splitting of a campaign that exceeds the daily quota. Tracking is real time and lives in the sheet. The company says it never stores your drafts, recipients or sheet contents.

Why it is not a cold email tool

Three reasons. YAMM runs inside one Google account per licence, so there is no rotation across a fleet of inboxes and no way to spread 2,000 sends across 40 mailboxes the way a sequencer does. Its daily limits are Google’s, 400 on Gmail and 1,500 on Workspace, and Google will rate-limit an account that pushes them with unsolicited mail. And it sends from the account you install it in, which for most people is their main domain, the one domain cold email infrastructure exists to protect. For personalised one-off campaigns to people who know you, warm follow-ups, event invitations and the like, it is excellent and almost free.

Who YAMM is for, and who should look elsewhere

YAMM suits individuals and small teams sending personalised one-off campaigns or warm follow-ups from their own Gmail or Google Workspace account at the lowest possible price. It is a poor fit for cold email at volume. Mailmeteor and GMass are the usual Gmail mail-merge comparisons, and for cold outreach the dedicated sequencers, Smartlead, Instantly and lemlist among them, are the tools to look at; we have not reviewed them yet. The sequencers category lists every tool we have reviewed with its score.

Using YAMM with PureMail

If you want to use YAMM for outreach at small scale, run it from a Google Workspace inbox on a secondary domain rather than your main one. A Google Workspace inbox from PureMail is exactly that: a warmed account on its own domain, with DNS done, that keeps your primary domain out of the picture. Keep the daily volume well below YAMM’s quota, verify the list first, and move to a sequencer once you need more than one or two inboxes.
