Internal provider flow

When you click Send on a campaign, this is what happens:

1. The campaign is locked and counts your active subscribers. It shows as Sending.
2. Each subscriber gets their own copy, sent through your store's email sending (the same as order emails).
3. A personal unsubscribe link is added to the bottom of each email, and a one-click unsubscribe option is included for Gmail and other inboxes.
4. Anyone who has unsubscribed or whose email has bounced or been blocked before is skipped.
5. When it finishes the campaign shows Sent, with how many emails went out and how many failed.

A campaign can be sent only once. To send similar content again, create a new campaign.

Large lists take time. Emails go out one after another. A list of a few thousand can take a while to finish; you can leave the page.
