Once here, click on the button that says “Add New Form.”

The form creation interface is comprised of three components:

  • HTML text editor for modifying the markup code for the form design directly
  • A simplified menu for adding new fields and customizing certain options in your form
  • A preview window for visualizing any changes that you make to the form

To add a new field to your form, you just have to select one of the contact attributes that you have set up in your contact database in Sendinblue (e.g. age, gender, country, etc.). If you don’t see the attribute that you want to use in your form, it may be because you haven’t added it as an attribute in your Sendinblue database.

To fix this, just log into the Sendinblue platform directly and add the attribute that you wish to use for your form. Then, you can go back into the form builder and select this attribute for the new field.

Further down the page, there are a few more options for customizing your WordPress newsletters subscription form:

  • Adding a Captcha
  • Adding a Terms & Conditions acceptance checkbox
  • Personalizing the theme of the form

Configuring the signup process for new contacts

Once you have created the form design, you’ll need to define the signup parameters:

  • Which contact list new subscribers will be added to after filling out the form
  • Whether or not to send a confirmation email
  • Whether or not to use a double opt-in process
  • URL for the subscription confirmation landing page (if you have one)

After assigning the setting up the different parameters of your newsletter campaign (subject line, sender name, etc.), you’ll have a few options for starting your email design:

  • Creating a new email template from scratch with the responsive Drag & Drop Editor
  • Using a recent message or saved template as a starting point
  • Starting with one of our free customizable templates located in the “Template Gallery

If it’s your first newsletter, it might be a good idea to choose one of the newsletter templates from our template gallery and customize the text, colors, and images in our Drag & Drop Editor to create the message you want to send.

If you’re looking for more of a fresh start, you can also just go straight into the Drag & Drop Editor and create your own design by dragging the pre-formatted blocks into your design and adding in your content.

After completing your email design, you’ll reach the “Recipients” step. This is where you select which list you want to send your newsletter to. You can also select specific segments of contacts within a list based on different attributes (gender, age, geography, previous email engagement, etc.).

For example, you can select all of the contacts in a list who opened your previous campaign.

Once you’ve defined your segmentation conditions, click on the button “Update recipient count” to see how many contacts are in your segment. From there, you can decide if you need to adjust your targeting or not.

5. Tips for sending a successful newsletter

You should now have a clear idea of how you can integrate a subscription form on your website and set up your newsletter directly from your WordPress site.

But before you hit send on your newsletter campaign, here are a few tips to ensure that your newsletter makes a lasting impression with your subscribers and keeps them coming back for more.

Include only your best content

Choose the content or products that you think are most relevant to your readers’ interests and your business goals.

When starting a newsletter, it’s very common to want to overload the message with all of the content that you have. But, your readers only have a small amount of attention that they can afford to give. You have to prioritize quality of content over quantity if you want to keep recipients engaged.

Rather than including too many links to different pages and articles, try adding certain product promotions or articles according to a specific theme — or better yet, tie the content in your newsletter to what’s actually new with your business. It is a NEWSletter after all. 😉

If you’re looking for having trouble finding the right theme for your newsletter, you can always go with seasonal events (e.g. end of the school year, winter holidays, etc.). For example, if you have a fashion blog, you might want to focus your June newsletter on the hottest trends for summer fashion. Then you can use warm colors and imagery invoking the beach and sun to create a timely theme that’s more engaging for your readers.

By varying your guiding theme for each newsletter you send, you can start to find your brand’s editorial voice in order to form a deeper connection with your audience.

Tell a story

Make sure your newsletter is highly engaging and unique by including original content directly in the email.

If you really want your readers to see the value in your newsletter, you need to treat it like a completely separate channel for editorial content rather than just a catalog of links pointing to various pages on your site.

Take for example the Daily Carnage email newsletter sent out by the Carney marketing agency. They provide unique content in every one of their newsletters to explain the linked content to the readers and increase engagement rates.

Although Carney uses editorial newsletter content to summarize articles and boost clicks, you can also create completely new content in your newsletter. For example, having a quick intro note to address the overall theme of the newsletter.

You can choose the content you think would be best for your audience, just make sure that it provides value for your readers.

Work the subject lines

Your newsletter subject line needs to be clear and enticing. This is the only way to guarantee solid and consistent engagement.

The email subject line is probably the single most important element in determining the open rate of your newsletter.

In the case of newsletters, the subject line should be both:

  • Alluring: Reading the subject line should make readers want to open your email.
  • Informative: It should give the recipient an idea of the theme or content of your email.

Over time, you should strive to create unique subject lines for your newsletters that are different yet still evoke the same voice that’s recognizable to your readers.

Use a consistent sending frequency

Set expectations with your customers on when they will hear from you by sending your newsletter at a regular frequency (e.g. weekly, monthly, quarterly).

Much like a newspaper or periodical, your newsletter should be delivered to your recipients on a fixed day and time. This allows readers to create a habit around when they can expect to receive your newsletter in their inbox.

Conversely, if you send your newsletter without any rhyme or reason as to the timing, you risk having increased unsubscribe rates because your contacts won’t be expecting to hear from you.

Once you choose the frequency that you want to use, it’s always a good idea to announce this frequency to new subscribers at the time of signup (or even before signup as part of the CTA in the subscription form itself). But, once you announce this frequency, it’s essential that you stick to it so that you don’t fall short of your readers’ expectations.
