Many email service providers only allow one unique email address in the database.
If the email address already exists in the database, the attempt to fix the typo will fail.
If this is the case, the misspelled email address should be deleted instead.
The described behavior is true for the following email service providers:
- ActiveCampaign
- Campaign Monitor
- ConvertKit
- Constant Contact
- Drip
- Gist
- HubSpot
- Klaviyo
- MailChimp
- MailerLite (will unsubscribe misspelled email address but fail to create new contact)
- Moosend
- Sendinblue
- Sendlane (will unsubscribe misspelled email address but fail to create new contact)
- Iterable
Other email service providers allow duplicate email addresses and treat them as different contacts. If this is the case the typo fixer will successfully fix the email address, and there will now be duplicate entries of the email address.
