Send emails using your own domain

Set up your domain in 2 simple steps

We provide an SMTP server and take care of all email sending settings. All you need to do is let us send emails using your domain. The configuration consists of two steps: adding records in your DNS and setting up the app.

DNS settings

These settings let you send emails from your domain. To make it work, you need to allow to send emails on your behalf. To do this, add two records to your DNS.

Please remember that settings can be different depending on your host.

Every record has its type, name, and value. 

SPF record

Name: It depends on the host. In most cases, it's the name of your domain, e.g. 

SPF should always be added as a TXT record.

Value: "v=spf1 mx a ~all".

DKIM record



Value:” should be replaced with your domain name.

DMARC record

Name :



“” should be replaced with your domain name.

More information about the construction of DMARC value here.

Changing the DNS may take a bit of time.


After adding the domain and making changes in your DNS settings, we recommend you send a test email and check if SPF and DKIM pass. (Otherwise, your emails may be filtered as spam.) DNS changes may take some time to run.

Domain on Cloudflare

The domain name in Cloudflare is removed automatically. Therefore, the DKIM and DMARC records will look like that:


DMARC: settings

Go to Settings -> Email domains and choose "Add new domain".

Fill in the fields:

Name - the main name displayed on the list of domains

Domain - the domain you want to use

Description - a short description of your domainIn the next step, validate SPF and CNAME. Validating SPF is needed for sending emails. CNAME is useful for verifying messages with an anti-spam system. We recommend setting DMARC as well. 

Domain sender settings 

We are able to add several senders from one domain. In the field, Settings, select the domain our sender will belong to. 

Name - the name of the sender, e.g. Customer Support, which will be displayed on our list of senders 

Sender name - the name of the sender, which will be displayed in the user's inbox

From email - displays, for the user, the email address the message comes from

Reply to - the email address your users can respond to

Description - a short description, e.g. what kind of message should be sent from this sender

How to check if the custom domain is configured correctly

The easiest way to check if the custom domain is configured correctly and records are valid is by sending a test email.

In "Settings" -> Email domains, click on the icon under Actions to get a drop-down menu. Choose the second option Send test email.

Enter the email address you want to send a test email to.

After receiving the message, check the parameters.

Below, you can see an example of a Gmail inbox.

When you open the message in the inbox, click the 3 dots icon on the right and choose Show original.

Check for the status, PASS, in both lines SPF and DKIM.

If there is no "PASS" in one of the parameters:

1. If there is "FAIL" in SPF( or in both SPF and DKIM), please check your records in your DNS settings.

2. If in you have "PASS" in SPF but "FAIL" in DKIM, please contact Customer Support via chat. Our agents will assist you; it may be related to custom settings for each user.

How to choose the sender/domain when sending email campaigns

In the last step of creating the campaign, choose which domain and sender you want the campaign to originate from.

Why is it important to send emails from your domain?

It influences spam filters, open and click rates, and increases the level of trust from your users.

Using the custom domain setting will positively affect the open rates of your campaigns, just as working with will yield higher results.
