I recently embarked on a side-project called DevMe, and I was told to start collecting emails even though I hadn't launched yet. (DevMe will be a website where developers can show off their interests, projects, job history and more). I tried many free bulk email services, such as Mailchimp, Tinyletter, EmailOctopus, and MailerLite. I used MailerLite for my latest email, but I'm not sure which service I'll use going forward.

Does your project have a mailing list? What (free) bulk email service do you enjoy using?
