Yet Another Mail Merge (YAMM) Review 2026: Features, Pricing & Honest Verdict
Yet Another Mail Merge (YAMM) is a Google Workspace add-on that lets you send personalized mass emails from Gmail using Google Sheets. With over 10 million installs and a 4.8/5 rating on 19,000+ reviews, it's one of the most popular mail merge tools in the Google ecosystem.
The appeal is simplicity and price. Plans start at $25/year. The trade-off: no automated sequences, no email deliverability tools, and you're still subject to Gmail's sending limits.
What is Yet Another Mail Merge?
YAMM is a Google Sheets add-on that connects to your Gmail account and sends personalized emails using spreadsheet data. You create your email template in Gmail as a draft, set up your recipient list in Google Sheets, and YAMM merges them together.
It's designed for newsletters, announcements, and internal communications rather than cold email outreach. Think school newsletters, nonprofit updates, and team-wide emails.
Key features
- Mail merge from Google Sheets: Personalize subject lines, body text, links, images, and attachments using spreadsheet columns.
- Real-time tracking: Open, click, bounce, and response tracking directly in your Google Sheet.
- One-click polls: Add simple polls to your emails without external tools.
- HTML/CSS customization: Design custom email templates with full HTML/CSS support.
- Contact segmentation: Filter and segment recipients in Google Sheets before sending.
- Scheduling: Schedule sends for a specific date and time (Personal plan and above).
- Personalized attachments: Attach different files to different recipients based on spreadsheet data.
YAMM works as an add-on for Google Sheets + Gmail. What's the main advantage of this approach?
Correct! YAMM's biggest strength is that it works inside Gmail and Google Sheets. No new platform to learn. If you can use a spreadsheet, you can send a mail merge.
YAMM doesn't bypass Gmail limits or improve deliverability. Its advantage is the familiar workflow. Gmail + Google Sheets means almost zero learning curve for anyone already in the Google ecosystem.
Pricing overview
YAMM is significantly cheaper than most email outreach tools:
| Plan | Price | Key Limits |
|---|---|---|
| Free | $0 | 50 emails/user/day |
| Personal | $25/year | 400 recipients/day, open/click tracking, scheduling, priority support |
| Professional | $50/year | 1,500 recipients/day + all Personal features |
Education and nonprofit discounts are available for groups of 25+ users. Even the top-tier plan is $50/year, compared to $30+/month for most cold email tools.
Full breakdown: YAMM pricing guide.
YAMM Professional costs $50/year. A typical cold email tool costs $30-50/month. How much do you save annually with YAMM?
Correct! At $50/year vs $360-600/year, YAMM saves hundreds of dollars. The catch is you get far fewer features. No sequences, no warmup, no A/B testing. You're paying for simplicity, not power.
The savings are substantial: $310-550/year. But YAMM is a different category of tool. It's a mail merge add-on, not a full cold email platform. The price reflects the feature gap.
Pros
- Extremely affordable. $25-50/year is a fraction of what most outreach tools charge monthly.
- Very easy to use. If you know Gmail and Google Sheets, you can send a mail merge in minutes. No onboarding needed.
- Familiar workflow. Works inside tools you already use daily. No context switching to a separate platform.
- Real-time tracking in Google Sheets. See opens, clicks, bounces, and responses update live in your spreadsheet.
- Proven reliability. 10M+ installs and 4.8/5 on 19,000+ reviews. This isn't a new or untested tool.
- Great for newsletters and internal comms. Perfect for school updates, nonprofit announcements, and team communications.
Cons
- Gmail sending limits apply. You're still capped by Google's daily limits (typically 500/day for free Gmail, 2,000/day for Workspace). YAMM can't bypass this.
- No automated follow-up sequences. You can send one email. If you want follow-ups, you have to create and send them manually.
- No built-in email verification. You need to verify your list externally to avoid bounces.
- No prospect or contact finding. YAMM sends to lists you already have. It doesn't help you find contacts.
- Very limited templates. No template library. You design everything yourself or start from scratch.
- No spam protection or sender reputation tools. No warmup, no deliverability monitoring, no spam testing.
- No A/B testing. You can't test different subject lines or body copy within a single campaign.
- No warm-up features. Unlike dedicated cold email tools, there's no way to gradually ramp up sending volume.
- Email-only, no multichannel. No LinkedIn, phone, or SMS outreach.
- Not designed for cold outreach. Better suited for newsletters and internal communications.
You want to send a cold email campaign with 3 automated follow-ups to 5,000 prospects. Can YAMM handle this?
Correct! YAMM can't automate follow-ups at all, and Gmail's sending limits (500-2,000/day) mean 5,000 prospects would take days just for the first email. For this use case, you need a dedicated cold email tool like GMass, Instantly, or Woodpecker.
YAMM doesn't support automated follow-up sequences on any plan. And Gmail limits sending to 500-2,000 emails per day. For cold outreach with sequences, consider GMass (stays in Gmail), Instantly, or Woodpecker.
Who is YAMM best for?
- Teachers, schools, and educators sending announcements to parents and students
- Nonprofits sending donor updates and event invitations on a tight budget
- Small businesses sending newsletters via Gmail
- Internal team communications and company-wide announcements
- Anyone needing basic mail merge on a budget who doesn't want to learn a new platform
Who should look elsewhere?
- Cold email outreach? GMass stays in Gmail but adds sequences and warmup. Instantly and Woodpecker are full cold email platforms.
- Link building outreach? MentionAgent ($99/mo) automates the entire workflow. No manual prospect finding, no campaign building.
- Multichannel outreach? Lemlist and Reply.io handle email + LinkedIn + calls.
- High volume? Instantly and Smartlead offer unlimited sending accounts and aren't capped by Gmail limits.
