In LinkMyAgency it’s possible to send an automated mail when you want to invite customers to link their platforms to your account. 
If you do not adjust anything at all, we send out the standard template. But you can also make your own. This is how.

First. Head over to Settings > Emails.
From here you can click on the Share Link E-Mail and start editing. You can also add several languages by clicking the Add language button. Note: this will make a copy of your existing template. So if you want to design the template here and there you will save time if you set-up your template first. 

In here you can drag and drop your desired Text, Images, Buttons and eventually HTML. E.g. when you want to include your own e-mail signature.
