# Send the email

A well-designed, easy-to-use interface. Snappy mail delivery without any backlogs like SendInBlue. WordPress site works far better & API documentation is very clean and understandable.

Pekka G. Freelance art director & web developer, Well-designed service

I reached out to support for an issue that was on my end. They responded very quickly and were eager to help. They truly cared about solving my issue even though I am still on the free tier for now.

Excellent deliverability, instant sending, powerful API, complete email analytics (opens, clicks, bounces), fast support. They have a great dashboard with a vast amount of valuable data.
