Automatically create SPF, DKIM and DMARC for your cold email mailboxes

Stop wasting time creating DNS records and let us do the heavy lifting for you.

We built Mailreef for people who send a lot of cold email

Here’s how automatic SPF, DKIM, and DMARC setup works


Log Into Your Mailreef Account

Under your Mailreef account, you will have access to the main dashboard where you can immediately get started registering a new domain.


Click on “Buy A Domain”

Every domain registered through Mailreef will automatically
have its SPF, DKIM, and DMARC records configured
automatically, without the need for you to do any additional configuration of your domain's DNS.


Enter Your New Domain Name

Under the domain registration screen, all you need to do is
enter in the domain name and TLD extension you wish to
register, and include any website link for your business if you
wish to set up a 301 redirect. Once you click on “Buy
Domain”, you are all set!


Mailreef Takes 30
Seconds To Spin Up A New Domain & Mailbox.

A study across 200k+ sent emails has shown that Mailreef outperforms Google, Microsoft, and Zoho’s deliverability when looking at cold email open rates. All other providers utilize shared IP addresses that directly hurts deliverability. Mailreef provides all users with a dedicated IP address, allowing you to be in full control of your deliverability rates.
