Pitfalls of using your ISP or running your own mail servers for reliable message delivery:

ISP are not optimized for transactional email and often not configured correctly for reliable delivery to the inbox. Many have restrictions and bad IP reputations that may impact your deliverability.

Running your own mail server while fun, come at a premium and requires expertise to setup and maintain. You may end up “burning” your office IP address if too many people complain and it can be difficult to change these settings.

How we maintain our IP reputation:

We maintain a very strict anti-spam policy. Proactive monitoring of mail traffic allows us to detect abuse quickly and stop that mail before it goes out and damages our reputation.

Outbound SMTP features included in all plans:

  • Maintain a very strict anti-spam policy
  • Proactive monitoring of mail traffic to detect abuse
  • Direct feedback loops with major email providers
  • Multiple Delivery Ports available – Relay mail to any of the following ports: 25, 587, 2525, 10025
