Why is CentricSell Mail so much cheaper than SendGrid and Mailgun?

1. Bring Your Own Accounts or Server

We do not provide, resell, or bundle ESP accounts. You connect your own AWS SES, SendGrid, Mailgun, or VPS. You pay providers directly at cost, while CentricSell Mail charges only a flat subscription for the management and failover platform.

2. Unlimited Sends on Every Plan

We don't charge per email sent. Emailing your verified contact list 10 times a month costs the exact same subscription price as emailing them once.

3. Automatic Multi-Provider Failover

Route through Amazon SES for your bulk volume, and automatically fail over to SendGrid or Mailgun if SES throttles or experiences an outage — with zero lost emails.
