Email Deliverability

Leave delivery, SPF and DMARC to Flowmailer!

You will never have tot worry about your deliverability again. Together with you, or your IT department, we'll make sure you meet the requirements for SPF, DKIM, and DMARC.


SPF (Sender Policy Framework) defines if an email sender is lawfully sending his messages under the sender's address. SPF prevents your emails from being seen as spam by an ISP and your recipient. Actual spam is being reduced.


DKIM (Domain Keys Identified Mail) is a method that enrichtes emails with a cryptographic signature. This signature will tell if the email truly contains valid information from a authorized sender. Flowmailer provides your emails with unique DKIM signatures, taking over a few difficult tasks.


DMARC (Domain-based Message Authentication, Reporting and Conformance) is a protocol you as a sender should use. With DMARC, your recipient is able to check if the message your sending is authorized by the named sender. DMARC also checks if the email hasn't been changed along the way. This prevents phishing. Flowmailer supports DMARC and is ready to help you with it.
