Fourteen features, one sidebar. Built for people who already run their business inside Google Sheets.
Email only the rows that match your rules.
Build conditions like Payment = Pending, Status = Approved or Score > 80. Mailvern scans your sheet and emails only the rows that match — every other row is left untouched.
Every column becomes a placeholder.
Drop {{First Name}}, {{Invoice}} or {{Due Date}} anywhere in the subject or body. Mailvern fills each email with that row's real values.
Save once, reuse forever.
Store reminder, onboarding and follow-up templates in your workspace and load them into any sheet in one click.
Send at the perfect local moment.
Queue a campaign for later today or next Monday morning. Mailvern sends on time without you opening the sheet.
Set it once, let the sheet work.
Auto Run re-checks your conditions on a schedule and emails newly matching rows — perfect for invoice reminders and lead follow-ups.
Know what happened, per campaign.
A clean dashboard with sends, opens, failures and per-campaign trends so you can prove the work.
See who actually read it.
Optional open tracking writes results back next to the row, so your sheet stays the single source of truth.
Send as the right identity.
Send from billing@, careers@ or any verified Gmail alias or delegated address on your Workspace account.
See which recipients replied.
Reply tracking will surface who answered your campaign and write that status back next to the row, alongside opens.
Nobody gets the same email twice.
Mailvern remembers which rows it has already emailed and skips them on the next run — even with Auto Run enabled.
Large lists, respected limits.
Sends are batched and paced to stay inside Gmail quotas, so big campaigns finish cleanly instead of failing halfway.
Beautiful email, no code needed.
Write formatted emails with headings, lists, buttons, images and links — or paste your own HTML.
Your data never leaves the sheet.
Mailvern runs as a sidebar inside Sheets. No exporting, no importing, no CSV files, no copy-paste.
Sent from your own Gmail.
Emails go out from your own Gmail account, so they land in Sent and thread naturally with replies.
Illustrations of the sending controls, email editor and analytics you get with Mailvern.
Use equals, contains, does not contain, greater than or less than, preview the exact rows that match, then send. Everyone else in the sheet is left alone.
