3. Periodically,we check and maintain our servers in order to serve you 98% deliverability!

Special Features:
  • SSL Connection to both SMTP and WEB servers so all of your data can be secure.

  • - Deliver rate
    - Open rate
    - Server Health
    - ...and many more statistics available in our management dashboard.


We provide professional SMTP servers that work in a new way compared to other SMTP providers.
Usually there are two types of emails by means of delivery speed.Instant (transactional) and mass.
We encourage you to use our service for mass email campaigns.
Our statistics show that sending 90kb email to 30 000 subscribers takes about 24 hours using Gutuma newsletter online and even less with our android app!
We don't know how our competitors qualify in terms of time but this way we achieved 98% deliverability... And all in INBOX!

If having troubles,direct communication with us is strongly advised,as sending so many messages is serious business.

* As of 10.11.2016 SMTPBOXES doesn't allow free messages,because of mass phishing attacks made via our free profiles.
