Email Infrastructure

How we paved the way to the inbox

You might not realize it when you look at emails in your inbox or when you're sending out emails from your campaign tool, but it took a long way for them to get there. Like railroads and power grids, the internet (and thus email) relies on invisible infrastructure to get traffic across.

Email Infrastructure


Whether you're a small sender or send out millions of emails each day, Flowmailer has your back. Our infrastructure is flexible and designed for optimal peak performance. The Flowmailer email infrastructure is completely self-hosted in the European Union, guaranteeing GDPR compliance and data security.

How it works

Regardless of where you're sending emails from - their journey is almost the same. You click 'send' in your digital campaign tool, your CRM triggers an auto-reply, or your webshop sends out an order confirmation: all email flows through the email infra.

After the email leaves your network, it connects to a Mail Transfer Agent (in our case the FlowmailerMTA). After that, the MTA communicates with the receiving inbox via a message protocol called Simple Mail Transfer Protocol (or SMTP).

Our platform takes the data you want to process through it and takes it on from there. It saves a copy of the original message and processes it the way you want to. You either enrich the email with a template or various features, or you can deliver your email 'as-is' - however you want your emails to look in the customer's inbox.

Flowmailer infrastructure

Flowmailer's infrastructure is built to always choose the optimal road for your email. By using carefully put-together IP pools and intelligent routing, we make sure that you're emails are not queuing up behind someone else's. The information we then get from the receiving mail server is looped back to the platform and presented in the Flowmailer Dashboard stats.
