Why self-hosted SMTP?

Whether you are a marketing company with the need for a mass mailing solution or a small webshop in need of sending transactional emails, you need to have an SMTP server where you can connect your application for sending emails. Due to the nature of complexity around setting up an SMTP system, hosted SMTP providers such as mandril, amazon SES, sendgrid etc. have emerged, with numerous alternatives. However, they all suffer from a common problem, they get abused by spammers. To combat that, they have very trippy antispam rules for their customers, and shuts down customer accounts whenever any suspicion arises. This is generally good, but it does not fit with all SMTP users. Sometimes you may need to send a mass email campaign over a very short time for legitimate purposes, and the SMTP providers wont let you do it, especially if your list is not up-to-date. On top it, you usually share the IP space with other customers of these ESPs, whose bad behaviour may ruin your own reputation.


Setting up your own SMTP server can seem daunting if you are not familiar with all the intricate details of email deliverability. SPF, rDNS, FcRDNS, DKIM, Domainkey, DMARC, Feedback Loop Processing - if these acronyms look daunting to you, you are not alone. Add to that checking IPs regularly against blacklists, keeping the configuration secure to not become an open relay for spammers, proper bounce management system to avoid sending the invalid and inactive email addresses.

SMTP server cluster

If your sending volume is significantly higher, we can setup nodes of servers that acts as a cluster with redundancy, so that even if one of them is down, the others will be available for sending, without any action on your part. You can rent servers from different hosting companies or cloud providers and we will bring all of them under one single gateway. You only point your application to one single IP, not fiddle around with multiple IPs.
