Currently there are lot of tools which help to verify the email address to reduce the bounce rate. By email verification I do not mean only syntax. I am talking bout email address being valid and deliverable. Does exact target have any provision to achieve the same? Is there any facility in exacttarget where I can load a bulk file containing email address and exacttarget can verify which email is valid or invalid.. Please advise.
I don't think marketing cloud has an email verification tool. The list detective feature will validate some common errors in email address and won't send emails to those address. You should be looking at 3rd party like Experian Data Validation.
check out address endpoint at https://developer.salesforce.com/docs/atlas.en-us.noversion.mc-apis.meta/mc-apis/routes.htm You can check for the same things list validation does, which isnt perfect but a good start. You could also build this into an excel macro to validate if needed
