Short text version: You can use an open source newsletter software called Mailtrain, link: https://mailtrain.org/
And use AWS SES with it, also if you send emails from EC2 with SES, you can send up to 62000 emails/mo for free, so you only have to pay for the EC2 Instance, with VAT that's about $7. For more info read this: https://aws.amazon.com/ses/pricing/
To run the stable version of Mailtrain, you need 1vCPU and 1GB of ram so you only have to pay for the EC2 server and you can send up to 62k emails for free, then only pay $0.1 for every 1k email sent.

Yeah it isn't for everyone, but taking into consideration that a lot of indiehackers code the product/have a technical co-founder I think this is a great way to save some money when you start, for me it even helped a lot with increasing the delivery rate too.
