I got this email delivery service a few days ago, and after my tests, I'm very satisfied. I haven't tested it in production for bulk email campaigns yet, but I wanted to leave a review already for others who might be interested because the deal is ending soon.

The dashboard has a clean and intuitive design. The domain setup worked smoothly. The integration with my SMTP (FluentSMTP) and my Marketing CRM (FluentCRM) also worked without any issues. I also connected it with my automation tool (Pabbly Connect) via API easily.

- One recommendation to the team: Since the SMTP credentials are inside the API Keys option, please change the name on the menu to "SMTP & API Keys" and also the button inside to "Add SMTP & API Key" to make it clearer and easier to find. That was a bit confusing.

- Another reminder for SumoLings: This is a service focused on email delivery (ESP), and it's not a tool to manage your marketing newsletter or campaigns, even though it has basic functionality for that. This means you'll probably still need a CRM/Marketing tool for proper newsletter and marketing campaigns.

Wishing you all great success in 2026!
