Verify emails before importing to Mailmeteor
Mailmeteor is a mail merge tool for Gmail and Sheets. A spreadsheet is the usual source for a mail merge, which makes it easy to verify the sheet as a CSV before merging.
Example
A sample file (fictional data)
| first_name | company | result | import | |
|---|---|---|---|---|
| ana@northwind.example.test | Ana | Northwind Studio | valid | yes |
| info@brightside.example.test | Brightside Digital | role | review | |
| raj@quill.example.test | Raj | Quill & Co | catchall | test batch |
| bob@gone.example.test | Bob | Gone Ltd | invalid | no |
Fictional rows. The import column is your decision per result; add it after you download results.
Import only what you decided to send
Sequences send from your own mailboxes, so every bounce counts against your domain. Import valid addresses; hold role for a deliberate choice; put catchall into a small test sequence; retry unknown later; never import invalid or disposable.
Keep the file you imported
Download results with the original columns, filter on result, and import that file. Keep the verification date so you know when to re-check before a follow-up campaign.
