Checklist After Migrating to MailPoet 3
The entire process of migrating should take about one hour in total in most cases.
Here's what you need to check once the migration script has successfully run:
1. Update your forms
Update your forms in your theme, widgets, sidebars, and shortcodes. Otherwise, your subscribers might join a list on MailPoet version 2 and they won't be automatically synced with your MailPoet 3 lists.
2. Templates and Emails
You will need to recreate your templates because we use an entirely new template system and newsletter editor in MailPoet 3. You'll also need to recreate your Post Notifications and Welcome Emails if necessary.
Also, check your Signup Confirmation email content.
3. Archive Page
Update your Archive page if you use that: the shortcode [wysija_archive] should be replaced by [mailpoet_archive]. Your new archive will be empty because we don't migrate the archive. You can leave the old shortcode if you still want to display the newsletters sent with MailPoet 2 as long as you keep the old plugin installed and active;
4. Review your subscriber's list
After migrating all your subscribers from MailPoet 2 to MailPoet 3, we strongly recommend running the imported list through a cleaning service if you're planning on sending with MailPoet Sending Service for the first time.
5. Premium license migration
The MailPoet 2 licenses will be automatically migrated to our new MailPoet 3 system. You can find your new Premium key on our new account manager.
6. SPF and DKIM
You will need to remove DKIM signature from your DNS. The plugin doesn't sign emails with DKIM anymore. Note that the MailPoet Sending Service does sign DKIM without the need for you to. Read more here.
If you are sending with the MailPoet Sending Service, you don't need to sign with SPF.
