Reliable SMTP mailboxes for cold email outreach with IP rotation, deliverability monitoring, fast setup, and scalable outbound infrastructure

IP rotation

We use IP rotation to send your campaigns from several different IP addresses, making your emails less visible to spam filters.

Send links right away

Your links are replaced with safe, trusted substitutes, so you can include booking links directly in your first email — without hurting deliverability.

Be sure your setup really works!

We run inbox placement tests every 3 days and display up-to-date health scores for each mailbox.
