I've exceeded Mailchimp's free tier and I was perfectly willing to pay, but I had in my head it was like $15 but its actually $31 per month. I feel like this is pretty steep and if anyone can suggest an alternative that's easier on the wallet I'd be glad to hear about it.
Thanks in advance.
I went with EmailOctopus. Their UI is awesome and their API is great. Prices are good too.
