Upload a CSV file up to 10 MB with a header row. Map one column to Email; other columns can map to first name, last name, or a custom field, or be ignored.

Rows with invalid addresses and duplicate rows within the file are skipped and listed in the import report, which you can download.

If an address already exists for the brand, its name, custom fields, lists, and tags are updated. Its subscription status is never changed by an import.

Only import people who gave you permission to email them for this brand. Purchased, rented, or scraped lists are not allowed.

Every contact records how and when they were added. Unsubscribes, hard bounces, and complaints are permanent unless the person opts in again.

To send from your own address you will add DKIM records (three CNAMEs) for your sending domain. We recommend a subdomain such as mail.yourbrand.com.

If you receive mail with Microsoft 365 or another provider, do not change your existing MX records. Sending authentication uses separate records.

Delivered means the recipient's mail server accepted the message. It does not tell you whether it reached the inbox or a spam folder.

Opens are estimates. Some apps load images automatically and others block them until you download pictures. The count is how many people opened the message.

Clicks are measured by redirecting links. Security scanners sometimes click links, so treat small counts with care.

You can cancel a scheduled or in-progress campaign. Recipients who have not yet been processed will not receive it.

Messages already handed to the email provider cannot be recalled.
