We use AtomEmailPro.
AtomEmailPro supports both traditional SMTP sending and web-based email sending through platforms like Gmail, Outlook, Yahoo, and more. It simulates real human actions in the browser, which helps improve deliverability and avoids spam filters more effectively. Plus, you can import a large number of email accounts, making it ideal for high-volume campaigns.
Compared to other tools like FastBulkMailer and BlackBulkMail, AtomEmailPro offers all their features—and more. It includes advanced functions like webmail automation, inbox improvement tools, email list cleaning, and even proxy support.
If you’re serious about email marketing, I highly recommend trying AtomEmailPro.
