So let's be perfectly honest… we've used at least 10 different email autoresponders over the past 20 years, and continue to use 3 different platforms today. Our favorite? ConvertKit. We love the simplicity of ConvertKit, even if it does lack some features advanced marketers may look for. Oh, and they are extremely friendly to affiliate marketers, so if that's your thing then ConvertKit will welcome you (unlike MailChimp)! We also tend to get better deliverability with ConvertKit campaigns, which is probably the most important aspect of an email autoresponder!
