Why did sending stop partway through?

Almost always the daily recipient quota on your Google account, or the 6-minute limit on a single Apps Script execution. Google allows 100 recipients per day on consumer accounts and 1,500 on Google Workspace accounts. Rows already sent are recorded, so running again continues rather than starting over.

Can the add-on read my Gmail?

No. It requests script.send_mail, which can only send. It requests no Gmail API scope, so it has no ability to read, search, or modify your mailbox.

My PDF still shows the placeholders. Why?

The placeholder name in the template does not match the spreadsheet header exactly. Matching is literal, including case and spaces.

Will re-running send the same email twice?

No. Each processed row is recorded, and a second run skips rows that already went out and retries only the ones that failed.

Email se.sato614@gmail.com. This is a one-person project; replies usually take one to two business days.

What to include: what you were trying to do, what happened instead, and — if a row was marked with an error — the exact text of that error. Please do not send us your spreadsheet or your recipient list; we do not want a copy, and we almost never need one to diagnose a problem.

Sending stopped partway through

This is expected behaviour, not a failure, and it has two causes.

The daily quota. Google caps how many recipients one account can email per day through Apps Script: 100 for consumer accounts, 1,500 for Google Workspace accounts. The quota resets 24 hours after the first send. No plan, payment, or tool raises it — this limit belongs to your Google account, not to us.

The 6-minute execution limit. Google stops any single Apps Script execution at six minutes. Long runs are therefore processed in batches that stop cleanly and resume.

In both cases, rows already processed are recorded. Running again continues from where it stopped rather than starting over, and nobody is emailed twice.

Placeholders are still visible in the output

A placeholder such as {{Name}} appearing literally in the finished PDF means the name inside the braces does not exactly match a column header in your sheet. Matching is literal:

Case matters. {{name}} does not match a header of Name.
Spaces matter, including a trailing space in the header cell — the usual culprit, because it is invisible.
Autocorrect in Docs. Typing quotes or dashes inside a placeholder can produce curly characters that no longer match.

Merge a single row and open the result before running a list.

Mail did not arrive

Check your own Sent mail. The add-on sends from your account, so anything it sent appears there. If it is in Sent, the add-on did its job and the question is one of delivery.
Check the recipient's spam folder. Bulk mail with attachments, sent to people who have not corresponded with you before, is filtered more aggressively.
Check the address. Rows whose address failed are marked with the error text Google returned.
Attachment size. Google's limit is 25 MB per message. A template with large embedded images can exceed it.

Permissions and privacy

Can it read my Gmail? No. The add-on requests script.send_mail, which can only send. It requests no Gmail API scope, so reading, searching, or modifying your mailbox is not something it is able to do.

Can it see the rest of my Drive? No. It requests drive.file, and you choose your template and output folder through Google's own file picker rather than typing a path. Access is limited to what you pick there, or what the add-on creates itself. It does not request the full drive scope, so it cannot browse or list the rest of your Drive.

Does my data leave my account? No. The add-on does not request script.external_request, the permission required to contact any outside server. Without it there is no mechanism by which your data could be transmitted anywhere. Full detail is in the Privacy Policy.

Billing

Cancelling. Cancel any time; the plan stays active to the end of the period you have paid for.
Refunds. If the add-on does not work as described and we cannot fix it for you, write to us and we will refund your most recent payment.
Invoices. Issued by the payment provider that processed your purchase; ask us if you cannot find yours.

Uninstalling

Open Google Workspace Marketplace → the Settings (gear) icon → Manage Apps → the ⋮ menu next to Bulk Email & PDF Merge → Remove. This revokes every permission you granted. Documents and PDFs already created stay in your Drive, because they are yours.

Doing it yourself instead

If you would rather run your own script than install anything, both guides are complete and free, with code you can keep:
