3. Click Manage subscription.
4. Click Cancel subscription and confirm.

Your plan remains active until the end of the current billing cycle. After that, your space becomes a free personal space.

How can I update the payment information for my subscription?

To update your payment information:

1. Go to your YAMM Dashboard.
2. In the sidebar, select your Space and click Billing.
3. Click Manage subscription.
4. Update your payment details.
   
   If you are removing a card to add a new one, first add the new card, and then you will be able to remove the old one.

Note: If you have a legacy plan purchased via PayPal, follow the steps in Update your PayPal payment information.

I bought a license, but it's not activated. What should I do?

In most cases, this happens because the wrong account is whitelisted or the payment didn't go through. There could be a typo in the email address. Even one different character counts (e.g., .org vs .com, gmail.com vs googlemail.com).

To verify, open a Google Sheet and check the email address in the top-right corner next to the blue "Share" button — this is the account YAMM uses. If it doesn't match your licensed account, switch to the correct one.

Spaces & Team Management

How can I manage seats in my Space?

If you are on a Pro plan with multiple seats (Google Workspace accounts only), you can manage seats from your YAMM Dashboard:

• To add seats: Go to your Space's Billing page and click Add seats. Select the number of additional seats and confirm. Learn more.
• To remove unused seats: Go to your Space's Billing page and click Remove unused seats. The downgrade takes effect at your next billing cycle. Learn more.
• To add members: Go to your Space's Members page and click Add members. You can only add members with email addresses in your own domain. Learn more.
• To remove members: Go to your Space's Members page and remove the member. Learn more.

You must be an admin or the owner of the Space to manage seats and members.

How can I transfer a license?

License transfers require contacting our support team.

We can only transfer a license between accounts of the same type: personal (@gmail.com) to personal, or Google Workspace to Google Workspace.

To request a transfer, complete the contact form and ensure that you send us the following information:

1. The source account that currently has the license: an email address for personal accounts or a domain for Google Workspace ones.

2. The destination account: an email address for personal accounts or a domain for Google Workspace ones.

   - For personal accounts, ensure that the destination account has YAMM installed and has sent at least one email with YAMM.

   - For Google Workspace, ensure that at least one email account from the destination domain has YAMM installed and has sent at least one email with YAMM.

3. The reason why you need the license transferred.

How can I transfer ownership of a Space?

If you are the owner of a Space, you can transfer ownership to another member:

1. Go to your YAMM Dashboard.
2. In the sidebar, select the Space, and click General.
3. In the Transfer ownership section, select the new owner and click Save.

Members with a Pending status can't become owners. After the transfer, you remain a regular member of the Space.

Sending & Tracking

How do I track my mail merge results?

YAMM comes with a built-in tracking tool. To enable it:

1. Select the Track emails opened, clicked or bounced checkbox before sending your mail merge.
2. After sending, the Tracking Report automatically opens on the right sidebar of your Google Sheet.

You can track opens, clicks, replies, bounces, and unsubscribes in real time. If you close the sidebar, reopen it from Extensions > Yet Another Mail Merge > Open tracking report.

Note: Tracking receipts are stored for around one year from the last recorded action (such as an open, click, or unsubscribe).

Learn more: How to track and measure your mail merge results?

How can I send a follow-up mail merge?

With follow-up mail merges, you can send a different message depending on how recipients reacted to your first email. You can target:

• Recipients who opened your email
• Recipients who did not open
• Recipients who did not respond
• All recipients

You can also choose whether to send the follow-up in a new email thread or in the same thread as your previous mail merge. The In same thread option requires the same subject, same recipients, and same sender email.

Learn more: Send a follow-up mail merge

YAMM doesn't merge my {{markers}}. What should I do?

If YAMM doesn't replace your {{markers}} with data from Google Sheets, it's usually due to invisible HTML tags in your Gmail draft that break the markers. This happens when you've edited your draft heavily or created it in another app.

To fix this: select the faulty marker in your Gmail draft and click the Remove Formatting button (the "T" icon with a strikethrough) in the draft editor. This removes hidden HTML tags causing the issue.

Make sure your marker names in the draft exactly match the column headers in your Google Sheet.

How can I schedule a mail merge for later delivery?

You can schedule mail merges up to 2 weeks in advance. A paid plan is required.

1. In Google Sheets, open your contacts list and start YAMM from Extensions > Yet Another Mail Merge > Start Mail Merge.
2. Click Schedule instead of sending immediately.
3. Select a date and time for delivery.
4. (Optional) Set a quota reserve to keep some sending capacity for other emails.

You can cancel a scheduled mail merge at any time before the scheduled send time from YAMM Dashboard.

Quotas & Deliverability

How does YAMM's quota system work?

YAMM's quota considers the number of recipients you send emails to and not the number of emails you send. So, for example, if you send one email to one recipient with two recipients in CC in the same email, that makes it three recipients, and YAMM counts three emails sent.

Your YAMM's quota depends entirely on Google and your Google account.

Google handles the quota and when it resets, and they can limit any accounts at any time for their own reasons.

Learn more: Available daily quotas

Why is my quota lower than expected?

The allotted daily quota depends on the plan you choose (free or paid plan), and in some specific cases, you won't be able to use all your quota because of Google restrictions.

Note that YAMM's quota is always lower than your Google account's quota, and it depends on it.

Learn more: Why is my quota lower than expected?

My mail merge stopped before completing. What happened?

YAMM may stop a mail merge before it finishes in order to protect your Google account from being rate-limited or deactivated. This can happen for several reasons:

• Too many bounces — A high number of undeliverable addresses signals a problem with your contact list.
• Daily sending limit exceeded — You may have used up your quota through other tools or by being signed in with the wrong account.
• Too many spam reports — Google temporarily reduces your quota if more than 10 recipients mark your email as spam.
• New account sending too fast — Google may get suspicious if a new account sends many emails immediately.

The quota renewal is handled entirely by Google. If Google rate-limits your account, we cannot reset it. We recommend reviewing the anti-spam rules and retrying later.

Learn more: Why was your mail merge stopped?

What are bounces and why do I get them?

Bounces occur when your emails can't be delivered to your recipients. There are two types:

• Soft bounces (temporary): recipient's mailbox is full, email is too large, server is down, or a connection timeout occurred.
• Hard bounces (permanent): recipient's email address doesn't exist, the domain doesn't exist, or the server has completely blocked deliveries.

You can find bounced emails under the YAMM - delivery issues label in your Google account. To reduce bounces, make sure your contact list is up to date and remove invalid addresses.

Learn more: What are bounces? Why do I get bounces?

My emails go to spam. How can I avoid this?

To reduce the chance of being blocked by Google or getting spam complaints:

• Warm up your account — Start by sending to a small list (<50 emails) and monitor the results before scaling up.
• Only email people who opted in — Never use purchased email lists. Recipients must have given you explicit permission.
• Include an unsubscribe link — Always give recipients a way to opt out of future emails.
• Keep your database clean — Remove bounced and invalid addresses regularly.
• Set up SPF/DKIM/DMARC — If you use Google Workspace, ask your admin to configure these email authentication records.

Troubleshooting

YAMM says I'm logged in with multiple Google accounts. What should I do?

This is an issue on Google's side, and it's outside our control.

Having multiple Google accounts logged in under the same browser window will affect YAMM's operation, and that's why we show that alert.

Instead of having multiple Google accounts logged in simultaneously, there's a better way of doing it.

The YAMM add-on doesn't load properly. What should I do?

If the YAMM menu doesn't load or only shows "Help", try the following:

1. Refresh your spreadsheet, wait a few seconds, and try YAMM again.
2. If you see "Configure form submission notifications" instead of "Open tracking report", click Extensions > Manage add-ons, then next to YAMM click Manage and select Use in this document.
3. If the "Extensions" menu doesn't appear at all, your file may be an Excel file (.xlsx). Convert it to a Google Sheet by going to File > Save as Google Sheets.

If the issue persists, try logging out from multiple accounts or reinstalling YAMM.

I get a "Server error" message. What should I do?

Server error messages in YAMM (such as "Server is not responding" or "A server error occurred") are caused by temporary issues with Google's servers, not YAMM's.

To resolve this:

1. Refresh your spreadsheet and try again.
2. If the issue persists, wait a few minutes and retry — these errors usually resolve themselves.
3. As a last resort, uninstall and reinstall the YAMM add-on.
