I am looking for reliable email service provider like mailchimp but paid with crpypto.
Is there any good software to send bulk emails cheap and without problems and not going to spam?
I couldn't find any reliable service that accepts cryptocurrency payments, but maybe it's best to run your own service and reduce risk of getting hacked, and nobody could ban you like Malichimp did.
After doing some research I found something that I didn't test myself, but you could try these open source alternatives that are free like ListMonk or Mailtrain:
