We use Postmark to send emails and manage newsletters directly from BlogBowl. Big thanks to Postmark for their reliable API and top-notch deliverability, which makes sure your newsletters actually reach your subscribers! We considered alternatives like AWS SES and Mailgun, but Postmark felt like a next-level solution—super easy to integrate and consistently reliable.
