How to add a Whatsapp button to email notification?

And is it also possible to insert a WhatsApp button into the email?

Hi Friederike,

Unfortunately, It's not possible to add a WhatsApp button to the notification email, While the feature you’re looking for isn’t currently available, rest assured we’re always working to add new services and features to Jotform. I've gone ahead and escalated your request to our Developer Team. When or if it's developed depends on their workload, how viable it is, and how many other users request it. If there are any updates, we’ll circle back to this thread and let you know.

Thanks for your patience and understanding, we appreciate it.
