Google reCaptcha v3 in the updated nuevoMailer ESP v.4.1

This new update for nuevoMailer ESP introduces Google reCaptcha v3 as an option for opt-in forms.

The coming 3rd party cookie restrictions which Chrome has already started to apply make the current captcha method inapplicable in some cases.
This is a problem especially for ESPs since your users want to put their opt-in forms in their own websites.
Therefore in 4.1 the current captcha method was updated (using partitioned cookies) and Google reCaptcha v3 comes as a new alternative, another option.

Read about all the new developments in nuevoMailer ESP v.4.1 here.

Autoresponders that are sent before an event

By definition and as the name implies autoresponders come as a response after an event has occurred. Such an event is for example sign-up to a list.

With nuevoMailer you can also create autoresponders that are based on custom subscriber fields of type date and fire before the given date.

The most typical example is Birthdays & Weddings. But it can be any type of anniversary dates or other dates that are very specific to your business (order date, visit date, expiration date and similar).

Here is how it's done:

Exact day comparison: how to use

  • For anniversaries you should not check this box because you are only interested on the day and month of the event.
  • Take the birthday example. You can create an autoresponder that sends a newsletter one week before: "Your birthday is coming - Make your plans now".
  • Some examples where you should check this box are the following:
  • Order dates, expiration dates, end of support dates, next-visit dates. For such cases you could create an autoresponder with a newsletter like "Your next [appointment] is on 5 days"

Final tip
If you plan to use this feature you should ideally combine it with external database import and synchronization. These articles explain how to import customers and order dates from WooCommerce and Prestashop but the concepts can be applied to any relational databases.

Adding a background image to your opt-in forms

In this simple step-by-step guide you will see how easy it is to add a background image to your opt-in form.


  1. Create or find a background image that you like. The image dimensions should be more or less similar to your form's width and height. It is ok and it is better to be larger.
  2. Upload the image in your assets folder. Tip: use the upload utility you have in your newsletter Html editor:
  3. Create and save an opt-in form or open an existing one. Go to your opt-in forms page and click this icon:
  4. Scroll down to this part of the code and add the highlighted code that you see here:
  5. Adjust the image URL to match your nuevoMailer installation URL and directory. Here are the lines to copy-paste:
    background-image: url("https://www.yourdomain/nuevomailer/assets/your_image.png");
    background-position: center;
    background-repeat: no-repeat; 
    background-size: cover;
  6. Click the "Update" green button at the bottom of the pop-up window to save your changes. 
  7. Click this icon to view the form: 
  8. Depending on the colors you used you may need to edit your form and choose different colors for your labels, input boxes and other form contents. When you edit a form, custom changes in the code are lost. So open again the pop-up to add the code for the background image.
  9. For the URL of the background-image and assuming your image is located in the assets folder, you may also use a relative path like this:  
    background-image: url("../assets/your_image.png");

What is CTOR and how it is calculated.

Different vendors have different ways of measuring CTOR. For example, Litmus defines it in this way:

"The click-to-open rate (CTOR) is how many of your opened emails were clicked on."

We believe this is accurate and we use exactly the same way in nuevoMailer reports.

The CTOR shows what percentage of those who viewed the newsletter clicked at least one link.

In other words we count the "clickers" within the "openers" group.

These groups may vary. The "view or open" of a newsletter can only be captured when the recipient explicitly allows image downloading when viewing the email. In most cases this is enabled by default (at least for subscribers that have you as a trusted sender). But one can still click a link without downloading images.

So with CTOR we focus on those who opened and clicked.
