I'm using the Typo Fixer. What if the suggested email address is already a subscriber, what happens when the Typo Fixer tries to fix the typo?

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 brevo (formerly 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 the described behavior is true for the following email service providers infusionsoft ontraport braze
