Overview
YAMM (Yet Another Mail Merge) is a mail merge for Gmail™ and Google Sheets™. It sends a personalized email to each person on a list in a Google Sheet, from your own account. Your spreadsheet then shows who opened, clicked, replied, bounced or unsubscribed, in real time.

YAMM has been installed more than 16 million times and is rated 4.7/5 by more than 18,000 users. When Google opened its add-on store in March 2014, YAMM launched there on day one.

HOW IT WORKS

1. Write your email as a draft in Gmail. Add markers such as {{First name}} where each person's details should go. Optionally add attachments.
2. List your recipients in a Google Sheet, one row per person, with a column for each marker.
3. Open YAMM from the Extensions menu of your spreadsheet and send yourself a test email.
4. Click "Send emails". Each person gets their own copy, sent from your address.
5. Track opens, clicks and replies as they appear in your spreadsheet.
6. Follow up in bulk when the time is right

DAILY LIMITS AND PLANS

➤ Free plan: up to 20 recipients a day.
➤ Paid plans: up to 400 recipients a day with a @gmail.com account, and up to 1,500 a day per user with a Google Workspace™ account.
➤ A new Google Workspace account starts with a 14-day free trial from Google and then a warm-up period. During that time, the limit is 400 recipients a day, or 100 a day when each email has its own attachment.
➤ Scheduling needs a paid plan.
➤ If your list is longer than your daily limit, YAMM automatically spreads the sending over several days.

WRITE AND PERSONALIZE

➤ Write your message as a normal draft, with your signature, images, spell-check, saved templates and Gmail Layouts.
➤ Personalize the subject line, body, links and images for each person. Use =HYPERLINK() and =IMAGE() in your sheet, no HTML needed.
➤ Send a different attachment to each person from Google Drive™, or several files per person. Docs, Sheets and Slides files are attached as PDFs.
➤ Write HTML and CSS directly in your draft, including media queries for mobile-friendly emails.
➤ Import names and email addresses from Google Contacts™ in one click.
➤ Add an unsubscribe link to stay compliant with CAN-SPAM and other email rules.
➤ Send yourself a test email before you send to everyone.

SEND AND FOLLOW UP

➤ Send to your whole list in one click, from your address or an alias, with personal or shared cc and bcc.
➤ Schedule a mail merge to go out later.
➤ Send a follow-up to the people who did not open your first email, to those who did not reply, to those who opened it, or to everyone. If the follow-up has the same subject as the first email, it can arrive as a reply in the same thread, so people see the full conversation.
➤ Filter or hide rows in your sheet to send to only part of your list.
➤ YAMM stops a mail merge automatically after too many bounces in a row, and warns you about addresses that bounced before.

TRACK

➤ Opens, clicks, replies, bounces and unsubscribes for each person, updated in real time in your sheet. Tracking is on every plan, Free included.
➤ Find your mail merges in your inbox with labels, or manage them with the companion Dashboard add-on in your inbox.
➤ See past campaigns in your dashboard: https://app.yamm.com

MORE

➤ Send an email when someone submits your Google Form™: to the person who answered, to your team, or both.
➤ Send one-click surveys that people answer from their inbox.

WHO USES IT

➤ Sales and recruiting: personal outreach to leads and candidates, with a simple CRM in a spreadsheet.
➤ Schools and teachers: one email per student or parent, with their own details or files.
➤ Nonprofits and associations: donor updates, member news and event invitations.
➤ PR and link building: personal pitches to journalists, bloggers and influencers.

YAMM has become an essential part of my workflow. The setup is quick, and the interface is clean and easy to navigate. It works seamlessly with Gmail and Google Sheets, making it incredibly simple to create and send personalized email campaigns without the hassle of traditional bulk emailing methods like BCC. What I appreciate most is how much time it saves while still maintaining a professional and well-structured format for each email. The tracking and customization features are very useful, helping me manage campaigns more effectively and improve engagement. Another standout aspect is their customer support. The team is responsive, knowledgeable, and genuinely helpful. They provide clear solutions and ensure that any issues are resolved quickly. Overall, YAMM offers a great balance of simplicity, efficiency, and reliability at a reasonable price. It’s a strong choice for anyone who needs to send batch emails regularly while keeping things organized and professional. Highly recommended.

It's always disappointing to rely on an app and then start to get charged for it once you've been using it for awhile. This happened with YAMM. Earlier this year, I was able to send up to 1,500 emails in a mail merge per day, and now I have to pay to send more than 20.

YAMM worked exactly as-expected. The interface was intuitive and user-friendly, the merged emails were correctly formatted, and the spreadsheet contact list for the merge was exceptionally convenient. This, for me, is far, far better than bulk-sending an email to a bunch of people using the BCC field. I'm very, very pleased with YAMM and will continue using it moving forward. Thank you!!

The service is priced monthly but charges a full year and doesn't refund the money when the service is cancelled 2 days later when I couldn't get the merges to work for my needs. The 1500 emails a day was limited to 400 not that I got anywhere close to that limit it is deceptive to tell you an amount then not honor it.

Oyu Tolgoi achieved Tyre Response Group’s highest audit score to date, reflecting strong performance in safety, workshop facilities, and emergency preparedness. While overall compliance is high, improvement is required in purchasing, maintenance, and data integration—particularly Tyre Management System tracking, SAP/Modular connectivity, and calibration registers. Addressing these gaps will align OT with industry best practice and deliver greater efficiency and risk control.

YAMM is not a flashy gimmick but a steadfast companion. It transforms the weary burden of writing countless emails into work both swift and humane. In seamless partnership with Google Sheets, each dull row becomes a living letter. It returns precious hours while keeping every message warm, sincere, and personal—proof that technology can serve humanity without diminishing it.

This app is ridiculous. Quota is poorly managed and communicated and indicated features, like picking up where you left of when your quota only covers part of a list, doesn't actually work. When you contact support, you receive a cut-and-paste response with a person's picture attached, but they don;t actually help you with your problem.
