This is the problem we face that the signatures are shown differently on PC and tabs/mobile phones.
By using Exclaimer Cloud, all email sent by your company will have a professional email signature added. That's across all devices such as mobiles, desktops, Macs, etc. The signatures are added after an email is sent, essentially being stamped to the message. That ensures everyone gets the same signature.
