In a marketo email I added the Example: <a href="sms:123456789">123456789</a> tag so when someone sees the email on their phone, they can click the number and it should open up in their messenger. When I sent myself a test I get a 404 page not found error. When I removed the tracking nothing happens when I click the number. Any ideas?
Email client: Outlook
Phone: Samsung Galaxy 7
I did a test using this code.
<a href="sms://+18016458495?body=I%27m%20interested%20in%20your%20product.%20Please%20contact%20me.">Send a SMS message</a>
And put it on a test landing page. [LINK]
I use a Google Pixel and it worked fine for me. I do know that this functionality is not supported 100%. I would need to do further testing to see what happens on a non supported device.
as far as email, I could not make this work in Outlook or gmail. I would assume the mail clients do not support it.
Hope this helps,
