Mautic+amazon ses
Heard about Amazon SES.
My answer above was kinda short because I was on my phone. But I really prefer SES along with Mautic to any cloud hosted tool. If you want an all-in-one solution and don't want to use SES, I'd recommend Active Campaign. They have a visual builder much like Mautic does where you can add conditionals, delays etc.
If you're emailing a lot, SES is also way cheaper then the cloud hosted version who are (for some reason) charging you for amount of subscribers, and not for emails sent (typically). I think on SES you pay something like $0.1 for 1k emails sent. I never really check my Amazon billing statements, all I know is that I run a whole bunch of stuff there: Lambda functions, S3, Cloudfront, SES, Route 53 and some API stuff, and my bill is never higher than 10$ a month ....
An example of what I use SES + AWS Lambda + API for at AWS: https://tobiesen.com the contact form here sends the JSON from the form to an API to the Lambda function, and send me an email via SES along with a Slack notification.
