I've used sendy extensively for the past 5 years.. which is the closest to Mautic.
My issue was and has always been deliverabity and IP reputation.
Since it's your domain sending emails, regardless of whether you're using Amazon SES etc.. the domain's reputation's always at risk.
I've had to change sending domains multiple times, but each time came up short.. I've mastered all MXtoolbox setups and continue to receive DKIM reports daily.
Mail-tester shows the content of my emails from 8/10-10/10
My question is, what sets your service apart from the commercial autoresponders like systeme.io and getresponse?
I'm not using systeme.io because at least the platform I'm using has a great reputation and my emails appear to be sent from systeme, not from my sending domain.
Why should I switch to your type of service and what benefits can I expect, considering ISPs will zap your sending domain the moment there're complaints, or simply because the domain doesn't have much authority?
Would really love to know.
Thanks
