@jamesepember If the addresses you're reaching out to have already opted-in to receive email correspondence from you, you're all good. Looks like this solution would be good when you don't have a large enough sample size for typical A/B and drip campaigns, and you just need to get a generic email out to an audience.
Hunted this via the creator @KevGroenendaal, a side-project that seems to deserve a lot more attention than it's got now.
It's very minimal and lets you mass-mail hundreds of recipients from OSX. All messages are sent individually.

I'd like to know when it got worrying to be flagged as a spammer here. It'd be helpful to see some use cases shown on the website.
