Step 1: Create a Twilio SendGrid Account

To integrate Free Mail SMTP with Twilio SendGrid, you first need to create an account.

Creating a Twilio SendGrid Account

If you haven’t signed up for Postmark yet, here’s how to create your account:

1. Visit the Twilio SendGrid Website.
   Go to SendGrid.com.
2. Sign Up for an Account.
   Click on the Start For Free button and complete the registration form with your details.

3. Verify Your Email Address.
   After submitting the form, you will be redirected to a page where you need to enter a verification code. This code will be sent to the email address you provided during registration.
   Check your email for the verification code, enter it on the verification page, and proceed.

4. Verify Your Phone Number.
   Once your email is verified, you will be directed to a page where you need to verify your phone number. Enter your phone number and follow the prompts to receive a verification code via SMS.
   Enter the code you receive to complete the phone verification process.

5. Log In to Your Dashboard.
   Once your email is verified, log in to your Twilio SendGrid account to access the dashboard.

Step 2: Create Your Sender Identity

To start sending emails with Twilio SendGrid, you need to set up a sender identity. There are two options available: creating a single sender identity or authenticating your domain. While both methods allow you to send emails, we recommend authenticating your domain for better deliverability and reputation management.

Adding a Single Sender to Your Twilio SendGrid Account

1. Navigate to Sender Authentication.
   In your Twilio SendGrid dashboard, click on Settings and then select Sender Authentication from the menu.

2. Add a New Sender.
   In the Single Sender Verification section, click the Get Started button.

3. Fill in the Required Information.
   You will be prompted to enter the sender’s name, email address, and physical mailing address. Complete the form and click the Create button.

4. Verify Your Sender Identity.
   A confirmation email will be sent to the address you provided. Open the email and click the link to verify your sender identity.

Authenticating Your Domain in Twilio SendGrid

Authenticating your domain is crucial for ensuring that your emails are recognized as legitimate. This process helps improve deliverability and removes the “via sendgrid.net” message from your emails.

1. Start Domain Authentication.
   In the Twilio SendGrid dashboard, go to Sender Authentication and click on the Get Started button under the Domain Authentication section.

2. Select Your DNS Host.
   Choose your Domain Name Server (DNS) host from the list. If you don’t see your provider, select Other Host (Not Listed).
3. Brand Your Links.
   You will be asked if you want to brand the links for your domain. It’s recommended to select Yes to have all links in your emails use your own domain.

4. Enter Your Domain.
   Input the domain you want to authenticate (e.g., example.com). If you prefer, you can also use a subdomain like mail.example.com.

5. Adjust Advanced Settings.
   Click on Advanced Settings and make the following adjustments:
   • Uncheck the box labeled Use automated security.
   • Check the box labeled Use custom return path and add a subdomain in the Return Path field.
   A subdomain is a part of your website’s address that can replace the “www” section (e.g., subdomain.example.com). Subdomains are useful for organizing different sections of your website; for example, a blog might be hosted at blog.example.com.
   In this case, the subdomain will be exclusively used by Twilio SendGrid for sending emails and will not be visible on your website. If you don’t have a specific subdomain in mind, using sg is a common practice.

6. Add DNS Records.
   Twilio SendGrid will provide you with specific DNS records (TXT and CNAME) that you need to add to your domain’s DNS settings. Keep this page open while you make the necessary changes.

7. Access Your DNS Settings.
   Log in to your domain registrar or hosting provider’s control panel to access your DNS settings. If you’re unsure how to find these settings, consult your provider’s documentation or support resources.
8. Add the Required Records.
   You will need to add the provided TXT and MX records to your DNS settings. Carefully copy the exact values from your Twilio SendGrid account, as accuracy is essential for successful verification.
9. Hostname Adjustments.
   If your domain is managed by a specific provider, you may need to adjust the Hostname when entering the records. For example, instead of entering sg.example.com for the TXT record’s Hostname, you would only enter sg.
10. Setting the TTL.
    You may see a TTL (Time To Live) field for the records in your DNS settings. If possible, set the TTL to one day (or 86400 seconds) to optimize caching.
11. Confirm Record Addition.
    After adding all the required DNS records, return to your Twilio SendGrid dashboard and check the box labeled I have added these records. Then, click the Verify button.

12. Monitoring the Verification Status.
    It can take up to 48 hours for DNS changes to propagate. If the verification does not succeed immediately, be patient and try again later. You can continue with the setup process for Free Mail SMTP while waiting for verification.
    Once your domain is successfully verified, you will see confirmation messages indicating that your domain is ready for sending emails.

Step 3: Generate Your Twilio SendGrid API Key.

To successfully connect Free Mail SMTP with Twilio SendGrid, you will need to generate an API key. This key allows Free Mail SMTP to authenticate your requests to Twilio SendGrid’s email delivery service, ensuring that your emails are sent securely and efficiently.

Generating an API Key

1. Log In to Your Twilio SendGrid Account.
   Access your Twilio SendGrid dashboard by logging in with your credentials.
2. Navigate to Email API Integration.
   In the left menu, click on Email API and then select Integration Guide.

3. Choose the Setup Method.
   You will be prompted to select a setup method. Click the Choose button under the SMTP Relay option.

4. Create Your API Key.
   Enter a name for your API key (e.g., “Free Mail SMTP Integration”) and click the Create Key button.

5. Copy Your API Key.
   Once the key is generated, make sure to copy it immediately. Keep this page open, as you will need to use this API key in the Free Mail SMTP configuration.

Step 4: Configure Free Mail SMTP.

Now that you have set up your Twilio SendGrid account, it’s time to configure Free Mail SMTP to use Twilio SendGrid for sending emails. Follow these steps to complete the setup:

Install Free Mail SMTP Plugin.

1. Log in to Your WordPress Admin Area.
   Access your WordPress dashboard.
2. Navigate to Plugin Installation.
   Go to Plugins → Add New.
3. Search for Free Mail SMTP.
   In the search bar, type Free Mail SMTP.
4. Install the Plugin.
   Click on the Install Now button next to the plugin, and then activate it once the installation is complete. Alternatively, you can download Free Mail SMTP directly from here.

Open the Plugin Settings.

1. Access Free Mail SMTP Settings.
   Once activated, find Free Mail SMTP in the left-hand menu and click on it to access the settings.

2. Select Twilio SendGrid as Your SMTP Provider.
   Click on the Add Provider button.
   From the list of available SMTP providers, select Twilio SendGrid.

Enter SMTP Configuration Details.

1. Connection Label.
   Assign a unique name to this connection for easy identification (e.g., “Twilio SendGrid Connection”). This is helpful when managing multiple SMTP setups.
2. Email From (optional).
   Specify the email address you wish to use for sending emails (e.g., noreply@example.com). This address can override the global email settings for the selected provider.

3. API Key.
   Paste the Twilio SendGrid API key you generated earlier into this field. This key is essential for authenticating your connection with Twilio SendGrid.
4. Priority.
   Assign a priority number to this connection. Lower numbers indicate higher priority, which helps determine the order in which connections are used for sending emails.

Step 5: Save Your Settings and Run a Test.

Once you’ve entered all the required details, click Save Settings to apply the configuration.

Next, find the Test button in the provider settings section of the Free Mail SMTP plugin.

If everything works correctly, your integration with Twilio SendGrid is complete!
