How to set up a custom sender email in Hotmart Send?

When sending campaigns or automations through Hotmart Send, the sender email is the address that appears to recipients of your messages. It is an important part of your communication, as it influences lead trust and brand recognition.

In this article, you’ll learn what the sender email is, the available options in Hotmart Send, and how to set up a custom sender email step by step.

What is the sender email in Hotmart Send?

The sender email is the address that appears as the origin of the message in the email header in the recipient’s inbox.

By default, Hotmart Send uses an automatic sender in the format contato@mail.hotmart.host . This address is ready to use and does not require any technical setup.

If you prefer, you can use a custom sender email created with your own domain, such as contato@yourdomain.com. This option helps reinforce your brand identity and can contribute to better open and engagement rates.

When should I use a custom sender?

Hotmart Send’s default sender works properly and can be used without any additional setup. Using a custom sender is recommended when you want to:

• Strengthen your brand identity in your emails
• Build more credibility with your audience
• Improve email deliverability and engagement

When choosing a custom sender, you’ll need to complete some technical steps to authenticate the domain used for sending.

What do I need to know before setting up a custom sender?

Before starting the setup, it’s important to check a few points:

• You have access to your domain’s DNS zone
• The email address that will be used as the sender has already been created on your domain (for example, support@yourdomain.com)
• The domain is not being used as a sender in another Hotmart Send account

Additionally, each Hotmart Send account allows only one sender email to be configured at a time. If you need to change the sender email in the future, you’ll need to redo the entire setup, as the domain authentication keys are updated with each new configuration.

How to set up a custom sender email in Hotmart Send?

The setup is done in two steps: first in Hotmart Send and then in your domain’s DNS.

After this step, Hotmart Send will automatically generate the information that needs to be configured in your domain’s DNS.

At this point, some technical terms will appear in the panel, such as DKIM, SPF, and DMARC. These represent records that authorize Hotmart Send to send emails on behalf of your domain and help improve message deliverability.

Why do I need to configure DKIM, SPF, and DMARC?

For Hotmart Send to send emails using your domain, you need to add some settings to your DNS. These settings are called DNS records and act as authorizations for email providers such as Gmail and Yahoo.

In summary:

• DKIM adds a digital signature to the email, proving that the message was sent from your domain
• SPF defines which servers are authorized to send emails on behalf of the domain
• DMARC instructs providers on how to handle messages that fail DKIM or SPF checks

Without these authentications, your emails may be rejected, sent to spam, or even harm your domain’s reputation.

What should I configure in my domain’s DNS?

To complete the custom sender setup, you need to add five DNS records in your domain panel.

These records are provided by Hotmart Send and must be copied exactly as shown in the platform. The five records are:

• 3 CNAME records
• 2 TXT records

Each record has a Hostname and a Value, which must be entered in the corresponding DNS fields. The names of these fields may vary depending on your domain provider.

After adding all records, go back to Hotmart Send, click Verify, and wait for the propagation period, which can take up to 72 hours.

With the records correctly configured, your emails sent through Hotmart Send will have greater security, a higher chance of reaching the inbox, and increased trust from recipients.
