Can anyone recommend an email service provider? One that delivers emails successfully without duplicates. Initially, my contacts notified me they were not receiving my weekly blog emails that I use to promote my business - when I asked Active Campaign for support they adjusted my account and the result was last week's email blog was sent out 8 times. In one day I have had 20 unsubscribes due to the glitch on the provider. Please share your suggestions for better email service providers.
