Why is a telephone number or address invisible in your newsletter?

Is there a telephone number, address or email address in your newsletter that your subscriber cannot see, or that is shown in a different colour? If so, your subscriber’s email client or device has automatically turned it into a clickable link, so the recipient can call, email or navigate at once. That link is given a colour that sometimes blends into the background. You will not see any of this in the editor or the preview, because it only happens when your subscriber opens the email.

If there are other differences between what you created and what your subscriber sees, take a look at why your newsletter looks different in the inbox than in the preview.

Many email clients and mobile operating systems (iOS and Android) recognise seven types of data in your text. On mobile devices, the operating system often does this itself, even if the email client does not.

What you can do about this

You cannot deactivate the recognition itself, as this happens outside Laposta. However, you can make sure that such a link remains readable. Sometimes you can also prevent it from being turned into a link, or simply create the link yourself.

This is the most important step and the only one that always helps. If the link colour is not configured properly, an automatically generated link may be given the same colour as the background of the block, making the text appear to have vanished. You can configure the colour in two places in the drag & drop editor.

Go to Blocks & Design → Global design → Body and adjust the ‘Link color’ right at the bottom of the left-hand pane under ‘Links’. You can read what else you can configure here in Configuring text formatting in your newsletter.

You can try to block the recognition by placing the text inside a <span>. In the text block, click ‘Source code’ and put the tags around the text, for example like this: <span>+31 6 12345678</span>.

The Source code button above a text box, with the telephone number between span tags below it

Laposta cannot guarantee that this will always work. A newsletter already contains a lot of HTML, and long newsletters are clipped by Gmail, for example. The ‘Source code’ button is intended for the text and links within that single text block, such as an anchor link, a tel: link or a span like this, and not for changing the structure of the block. You are responsible for any code you add yourself; see Can I add my own HTML code in the editor?.

You can also place the link yourself. That way, you decide which text is clickable and where it leads, and it will be given the link colour you have configured. For a telephone number, the easiest way to do this is via the editor’s link window, as described in Placing a phone number as a clickable link. In the source code of a text block, such a link looks like this:

<a href="tel:+31612345678">+31 6 12345678</a>
<a href="https://maps.google.com/?q=Dam+1+1012+JS+Amsterdam">Dam 1, 1012 JS Amsterdam</a>

The first line makes a telephone number clickable, and the second opens an address in Google Maps.
