Moonmail is a pretty awesome emailing service used by companies like Nespresso, Amazon, Circle, and many more. They switched from using a traditional approach to servers, from using RoR on EC2 to serverless and it's best explained in a case study by Carlos Castellanos where he details the journey from EC2 to AWS Lambda. - Source: dev.to / about 2 years ago
If you're not getting the right email addresses from ContactOut and it's bouncing back, you could always run the email addresses through something like emaillistverify.com to make sure they're valid before you try to email them. (you should do that always anyway to protect your email deliverability). Source: almost 2 years ago
