Web APIs and FBL Question


New Member
Probably silly question but just to confirm whether my understanding is correct ...

If I use SMTP provider that has a web api like mailgun or elasticmail for example, do they handle the bounce / unsubscribes and spam complaints? ie. they will post the email addresses of all 3 back to my MW app so I can exclude them from future mailings?

So there is no need for me to sign up to yahoo, hotmail, gmail to manage the FBL?
