Step 1: Create a Brevo Account
To integrate Free Mail SMTP with Brevo, you first need to create an account.
Creating a Brevo Account
- Visit the Brevo Website.
Go to Brevo.com. - Sign Up for an Account.
Click on the Sign Up Free button and complete the registration form with your details.


- Verify Your Email Address.
After signing up, check your email for a verification link from Brevo. Click Confirm my email address to activate your account.

- Provide Your Details.
At this point, you will be redirected to a page where you need to provide some information about yourself, starting with your name and company name.

- Enter Company Information.
Brevo will then ask for your company address. Fill in these details accurately.

- Additional Company Details.
Next, you will be prompted to provide information such as the number of team members, the size of your mailing list, and whether you plan to sell products online.

- Enter and Verify Your Phone Number.
After completing the previous fields, you will need to input your phone number. Once you’ve done that, click the Send verification code to continue. Once you receive the verification code, enter it in the designated field and proceed to the next step.

- Choose Your Plan.
After filling out all the required fields, you will be able to select a plan. For this setup, we’re going with the Free option, but the process is similar for any paid plans you might consider.

After setting up your account, you can move on to the next step.
Step 2: Authorizing Your Domain
To ensure successful email delivery, it’s crucial to authorize your domain in Brevo. This domain must correspond with the one used in your From Email address. For instance, if your From Email is pattie@example.com, you will need to verify the domain example.com in your Brevo account.
Setting Up Your Domain in Brevo
- Log Into Your Brevo Account.
Start by accessing your Brevo dashboard with your login credentials. - Go to Sender Settings.
Click on your company name located in the top right corner, then select Senders, Domains & Dedicated IPs from the menu options.

- Add a New Domain.
On the next page, find the Domains option and click on it. Click on the Add a Domain button to initiate the domain verification process.

- Input Your Domain Information.
Enter the domain you wish to verify (e.g., example.com). It’s advisable to use a subdomain dedicated to email sending, such as mail.example.com. Then click Add a domain.

- Authenticate Your Domain.
At this point, you can choose to either authenticate the domain yourself or share a link with someone else to do it for you. In this case, I decide to click on Authenticate the domain yourself. Then, click on Continue.

Adding DNS Records
After saving your domain, Brevo will provide specific DNS records that you need to add to your domain’s DNS settings. This step is essential for verifying your domain and ensuring reliable email delivery.
- Access Your DNS Management.
Open a new tab and log in to the platform where you registered your domain (usually your hosting provider). Locate the DNS management section for your domain.
💡Note
If you have trouble finding your DNS settings or feel uncertain about making changes, contact your hosting provider for guidance.
- Add the Required DNS Records.
In your DNS settings, look for an option to add new records. You will need to add the TXT records provided by Brevo. Ensure you copy the values accurately, as they are critical for successful verification.
We’ll explain how to add each DNS record in detail below, using example.com as a placeholder. When updating your own DNS settings, be sure to replace it with your actual domain name.
TXT Record (Brevo code):
- Host/Name: example.com
- Record Type: TXT
- TTL: 24 hours (or 86400 seconds)
- Text/Data: copy the value from Brevo

TXT (DKIM) Record:
You’ll have to add 2 DKIM records. An example could be:
- Type: TXT
- Name: mail._domainkey
- TTL: 24 hours (or 86400 seconds)
- Value: copy the value from Brevo


💡Tip
If you’re using GoDaddy to manage your DNS, make sure to set the TTL (Time To Live) to 1 hour. This value should be applied to all three DNS records.
TXT (Optional DMARC Record for Google and Yahoo Users):
Establishing a DMARC policy on your domain is recommended to meet the latest sender requirements from Google and Yahoo.
- Host/Name: _dmarc
- Record Type: TXT
- Text/Data: copy the value from Brevo.

- Verify Your DNS Records.
After adding the records, return to your Brevo dashboard and click the Authenticate this email domain button to check if the records are correctly configured.
DNS changes can take from 24 to 48 hours to propagate. If you encounter issues during verification, you can attempt to verify again later. Once Brevo verifies your records, you will see a green Value Matched status next to each record in your dashboard.
While you wait for the verification to complete, there’s no need to pause your setup process. You can continue with the next steps, but be sure to keep this tab open for future reference.

💡Important Note
If you are verifying a subdomain, make sure to use the same subdomain in the From Email setting in Free Mail SMTP (e.g., pattie@subdomain.example.com).
Step 3: Generate Your Brevo API Key
To connect Free Mail SMTP with Brevo, you will need to generate an API key. This key is essential for authenticating your email sending and ensuring secure communication between your WordPress site and Brevo.
Generating Your API Key
- Log In to Your Brevo Account.
Open your Brevo dashboard by logging in with your credentials. - Access the API Settings.
Click on your account name or profile icon in the top right corner of the dashboard, then select SMTP & API from the dropdown menu.

- Navigate to API Keys.
On the SMTP & API page, switch to the API Keys tab. - Create a New API Key.
Look for the option that says Generate a new API key. Click on this link to initiate the creation of your v3 API key.

- Name Your API Key.
A prompt will appear asking you to name your API key. Choose a descriptive name that helps you remember its purpose (e.g., Free Mail SMTP Integration).

- Generate the Key.
After naming your API key, click the Generate button. A new modal window will appear displaying your newly created API key.

💡Important Note
Make sure to copy this key and store it securely, as it will only be displayed once. If you close the modal window, you will have to create a new key to access it again.
- Copy Your API Key.
To copy the key, click the icon next to it.
Once you have copied your v3 API key, you can proceed to configure Free Mail SMTP by pasting the key into the appropriate field in the plugin settings.

Access your WordPress dashboard. - Navigate to Plugin Installation.
Go to Plugins → Add New. - Search for Free Mail SMTP.
In the search bar, type Free Mail SMTP. - Install the Plugin.

Enter SMTP Configuration Details

Assign a unique name to this connection for easy identification (e.g., Brevo Connection). - Email From (optional).
Specify the email address you wish to use for sending emails (e.g., noreply@example.com). This address can overwrite the global email settings for the selected provider.
💡Note
For best results, use a domain-specific email address (e.g., info@example.com) to enhance deliverability.
- API Key: paste the Brevo API key you copied earlier into this field. This key is essential for authenticating your connection with Brevo.
- Priority: assign a priority number to this connection. Lower numbers indicate higher priority in the fallback mechanism.

Optional Step: Backup Connection
Configuring a Backup Connection is optional and not necessary for completing your Brevo mailer setup. However, it is highly recommended to establish an additional connection to further enhance your email deliverability. This backup connection will automatically activate if your primary connection encounters any issues, ensuring uninterrupted email sending.
- Setting Up the Backup Connection.
If you decide to implement a backup connection, follow similar steps as you did for your primary connection. You can select a different SMTP provider or set up an alternative configuration with Brevo. - Save Your Changes.
After you have configured your mailer and any backup options, remember to click the Save Settings button to ensure all your configurations are applied.
Step 5: Save and Verify Your Setup
Once you’ve entered all the required details, click Save Settings to apply your configuration.
Next, navigate to the SMTP provider settings within the Free Mail SMTP plugin and locate the Test option. Perform a test to verify that everything is set up properly.
