SMTP2GO Just Works

Transactional emails...oh Transactional emails, how I adore you. Back in the day, we used to attempt to use Office 365 SMTP services for these types of emails (server notices, copy machine scan-to-email, networking gear notices, etc). What a disaster. Very, very difficult to get things to play nice with O365 email because of the tight security around it all, and the limitations. Then we attempted to do an in-house SMTP service on a Linux VM. Too much of a management and security nightmare. The box itself started getting hit with spam. Copy machines and printer All-in-one scanning to email was a non-starter because of their weird ways of configurations.

Geeze. Couldn't freaking win. That is, until we discovered SMTP2GO. Easiest setup, easiest service, and it just works, with a TON of ports, login/auth options, encryption methods, everything. Nothing will stop email delivery provided you have done the correct CNAME setup for the sender domain. You can even just straight up whitelist an IP address or subnet and it will accept email with no auth and no encryption for those really archaic devices on the net that need to send out some kind of transactional email. Highly recommend SMTP2GO and they remain an important part of our stack at our MSP.
