Email signatures after a merger or tenant migration
Two companies, two brands and often two Microsoft 365 tenants. How to handle email signatures after a merger, from day one to the tenant move.
A long email thread with the full signature on every message soon becomes more signature than conversation. The usual answer is a shorter signature on replies: name, job title and a phone number, and nothing else. In Footer365 that is two rules and about two minutes.
Every signature reaches people through a rule, and each rule says who it applies to and when. When someone sends an email, Footer365 works down your rules in order and uses the first one that matches. That is what makes a reply signature easy: put a rule for replies above your main rule, and replies are caught before they reach it.
New emails and forwards fall through to your main rule and get the full signature. Replies stop at the reply rule and get the short one. If you want forwards to be short too, add a second rule for Forwards only.
On a reply, Footer365 puts the new signature directly under what the person has just written, above the quoted earlier messages, where a reader expects it. The earlier messages keep the signatures they were sent with, because they are part of what is being quoted.
Test a rule on the same page lets you pick a person and an email type and see which rule and template they will get. It changes nothing, so it is safe to try as often as you like.
