Thank you for fronting the cost all these years!
Of course! Happy to do it.
In the past, I have accepted advertising as a way to offset the costs. In the future, I may no longer accept advertising since I expect my costs to be low enough. We’ll see what SES ends up costing me, and how much maintenance listmonk requires 
Aww, please do — HW is my no. 1 source of job ads.
Job postings will certainly remain! I just may do them for free, depending on how things shake out.
I switched my company to SES last year and it was a great success. They are a AWS shop though, I can’t comment on the costs unfortunately because the email usage was small and the bill was miniscule compared the rest of the services.
I must confess though every time I pay for anything email related my brain always wonders if I could build something to do this myself.
Most of the cost of self-hosting goes into getting your IPs removed from blacklists 
Microsoft especially is quite harsh.
Oh interesting, are blank lists just a blanket ban then? I guess the email servers have no way to distinguish between random emails and something you subscribe to.
Shocking to see Microsoft trying to profit off legacy design
