Download the WordPress plugin

The Sendinblue plugin for WordPress allows you to build subscription forms to grow your contact lists, manage the sending of your transactional emails, track your page visits, and more!

In this article, we will explain how to:

Before you start

Gather the following information prior to installation:

• Your Sendinblue account credentials
• Your API v3 key
• Your WordPress website admin access

Install the WordPress plugin

Download the plugin

1. Log into your WordPress dashboard as an administrator.
2. In the sidebar menu, go to Plugins > Add New.
   
   
3. Search “Sendinblue” to find the Newsletter, SMTP, Email marketing and Subscribe forms by Sendinblue plugin.
4. Click Install Now, then Activate.
   

Once installed, the Sendinblue tab will appear at the bottom of your WordPress sidebar menu.

Connect your website to Sendinblue

Now that the plugin is installed, connect your website to Sendinblue:

1. In the sidebar menu, go to Sendinblue > Home.
2. In the Access Key field, enter your API v3 key. Follow these instructions to find your API key in your Sendinblue account.
3. Click Login.
   

Congratulations! You have connected Sendinblue to your WordPress account 🎉

Synchronize your existing WordPress contacts

The synchronization of existing WordPress contacts to your Sendinblue account has to be done manually:

1. In the sidebar menu, go to Sendinblue > Home.
2. Click Sync my users.
   
   
3. From here, you can select:
   • The type of users (roles) you would like synced,
   • Which Sendinblue list(s) you would like the contacts to be added to,
   • Which attributes you would like synced.
     ²
4. If you want to sync different roles to different lists, follow this process again and set up sync rules for each list.

That's it! Your existing contacts have been synchronized to your Sendinblue account.

Synchronize your new contacts

There are two ways your new contacts can be synchronized to your Sendinblue account:

• By being identified by the Sendinblue tracker
• By subscribing to your newsletter

Sync new contacts who are identified by the Sendinblue tracker

Once you have activated Marketing Automation through Sendinblue, the Sendinblue tracker will collect all email addresses that are left on your website. There are several ways the Sendinblue tracker can collect an email address:

• After a contact creates an account on your website,
• After a contact purchases a product in guest mode,
• After a contact submits a contact form,
• Etc.

All contacts who are identified by the Sendinblue tracker are then added to your “identified_contacts” list as non opt-in contacts.

For example, if John Smith creates an account on my website, the Sendinblue tracker will retrieve his email address, and he will be added to my “identified_contacts” list:

Sync contacts who subscribe to your newsletter

Once you have added a subscription form on your website, we will automatically synchronize all contacts who subscribe to your newsletter. We will synchronize their data to the list you chose during the setup of your form.

For example, if I have a subscription form on my website and Jane Doe subscribes to my newsletter, she will automatically be added to the list I chose. All the information she provided in the form will then be automatically synchronized in my Sendinblue account:

Add a subscription form to your website

We offer two methods to create a subscription form to add on your website so that visitors can subscribe to your mailings and be synchronized to your Sendinblue account:

• Embed a Sendinblue subscription form on your website (Recommended)
• Create a subscription form on WordPress

Embed a Sendinblue subscription form on your website (Recommended)

To eliminate any conflict with other WordPress themes or plugins, we recommend you embed your subscription form created in Sendinblue on your website. Moreover, our form builder is easier to use and more powerful than the one you will find on WordPress.

To learn how to create and embed a Sendinblue subscription form on your website, check out our Create a subscription form dedicated series of articles. You can then embed your Sendinblue form in an Iframe on your website.

Create a subscription form on WordPress

You can also create a subscription form directly on WordPress using the Forms feature.

Step 1: Add a new subscription form

To start creating a new subscription form on WordPress: 

1. In the sidebar menu, go to Sendinblue > Forms.
2. Click Add New Form.
   

Step 2: Design your subscription form

Our form editor has a dual interface and also allows you to preview your subscription form:

1. HTML editor
2. Simplified interface for adding fields to your form, among other options.
   To collect more information from subscribers, select the field you want to add from the dropdown list. The options shown depend on the contact attributes you have set up in your Sendinblue account. Once you’ve filled out the information for your new field, click Add to form, and it will appear in the preview.
3. Preview window
   You can view any changes you make by refreshing the preview window.

Further down, you will find more customization options:

Multi-list subscription for subscribers to give their preferences and be added to a corresponding list Captcha to protect your form from spambots A compliance note and checkbox to agree to terms and conditions Custom form style to change the default theme of your subscription form using CSS

Step 3: Set up the sign-up process

1. Select which list subscribers are added to when they fill out your form.
2. Send a confirmation email to let them know they will start receiving your newsletter.
3. Set up a double opt-in process so they have to click a link in your confirmation email to validate their subscription.
4. Redirect them to a specific URL after subscription.

Step 4: Edit your confirmation message

Edit the text for success and error messages that appear on your subscription form after submissions.

Step 5: Add the subscription form to your website

3. Paste it into the WordPress editor for your chosen post or page.

To activate Automation on your website in just a few clicks:

To access your email and SMS campaigns statistics:

1. In the sidebar menu, go to Sendinblue > Statistics.
2. Set up a time period.
3. Click Apply.
   

Troubleshooting issues with the WordPress plugin

🛑 My subscription form is not working

You copy-pasted your subscription form from one form builder to another

Copy-pasting the code of your Sendinblue form into the WordPress form builder will result in your subscription form not working properly (and vice versa). You must create a new form in WordPress (or in Sendinblue) instead of copy-pasting the code from a form builder to another.

🛑 My new contacts are not synchronized to my Sendinblue account

Your contact was identified by the Sendinblue tracker

If your contact was identified by the Sendinblue tracker, only their email address will be automatically retrieved. You can find this information in your “identified_contacts” list in Sendinblue.

Your contact subscribed to your newsletter

To automatically synchronize your new contacts and their information, make sure you have added a subscription form on your website. This will ensure that your new contacts are added to your Sendinblue account and that they have opted-in to receive your emails. 

🛑 I'm not receiving any emails from my WordPress plugin

You are using 2 SMTP relays

If you are using 2 SMTP relays in your website, there may be some conflict happening. To make sure you're not using two SMTP relays, search for any SMTP plugin in your installed plugins (e.g. “Easy WP SMTP”, “WP Mail SMTP”, “SMTP Mailer”). If you notice one, disable it and send yourself a test email. This step will confirm if there is an SMTP plugin conflict.

SMTP is not enabled on your Sendinblue account

To be able to send transactional emails using Sendinblue, make sure your Sendinblue SMTP account has been activated. If it has not been activated yet, send a request to our support team.

SMTP is not enabled from your WordPress plugin

To be able to send your WordPress transactional emails using Sendinblue, make sure you have enabled the Activate email through Sendinblue option in the WordPress plugin. To check if you have activated this option, please refer to the Send transactional emails section above.
