Many domains limit who can send e-mail on their behalf. If you use Payt it is important to include us in the list of allowed entities, as we are sending e-mail to your debtors on your behalf.

Adding Payt to your SPF record

SPF is short for Sender Policy Framework. In an SPF-record you can configure which servers may send email from that domain. The receiving email server will decide which messages to block, distrust or allow through based on this SPF-record.

You can check if the SPF record is configured correctly by navigating to Dashboard -> Administration settings -> tab Email

If these instructions are outside your area of expertise you can forward these to your IT department.

I already have an SPF record

If you already make use of an SPF record on your domain then Payt will have to be included in that record. This can be done by adding the following to your SPF record:

Be aware of the underscore, as it is part of the requirements.

I do not yet have an SPF record

If no SPF record is configured on your domain you will need to create this record. A standard SPF record which includes Payt will look like this:

v=spf1 ~all

Keep in mind that the final SPF record in either case needs to be of the TXT type. The older type 99 is no longer supported.

Sender authentication

If many of your debtors are not receiving your emails, you can considering using the Sender authentication setup from our emailprovider.

Some email service providers as an anti-spam measure will check if the domain of the sending email adress matches the domain of the sending service. After configuring Sender authentication, email messages are sent from your domain. This means that in the email headers it is no longer visible that the email was sent via a Payt domain.

For example; the sending address as configured in Payt is and we send a new invoice to one of your debtors. In that case the domain of the FROM address is and the domain of the sending server is, which may result in the receiving server distrusting the received email message. If Sender authentication is active, the FROM and sending server domain would both be

Sender authentication requires a change in your DNS settings. Three CNAME records will have to be added that refer to our email provider Sendgrid. If you want to receive the setup instructions for Sender authentication, please contact our servicedesk.
