Contacts and channels

When the contact person changes

The silent cause of half the cases that stall.

Updated on 13/08/2026

It is the cause nobody suspects and it explains a huge share of dead cases: the person you write to left that company months ago. Their email may still be active, may bounce, or may be read by someone with no idea what it is about.

How to recognise it

SignWhat it usually means
It suddenly bounces after months workingThey left and the account was closed
It is delivered but never openedTheir mailbox is alive and nobody reads it
Someone else replies asking what it is aboutSomebody inherited the mailbox without context
They reply from a different addressThey have already changed and did not tell you

Important

The second row is the worst because it produces no error. The system says delivered, you assume it arrived, and the case waits for someone who no longer exists at that company.

What to do when it happens

  1. 1

    Fix it on the record, not just on that send

    Fix it only there and the next case fails identically.

  2. 2

    Ask who replaced them rather than sending blind

    A one-minute call to their switchboard resolves months of silence.

  3. 3

    Keep both contacts if they coexist

    Many companies have one for paperwork and another for invoicing.

How to catch it earlier

Watch out

When someone tells you they are leaving and gives you their replacement's details, update it that same day. It is the only moment you hold the right detail without hunting, and it vanishes the moment that mailbox closes.

Worth knowing

If a contact has opened nothing in a year, it is not a contact: it is an address. Treat it as such before launching an important request at it.

Can I have several contacts per company?

Yes, and you should: it halves this problem.

Is history lost when the person changes?

No. History belongs to the company and the case.

What if nobody at that company replies?

The main phone number. It is slow, and still faster than three months of silence.

A real case

The situation

A company has had no reply from a supplier in four months and assumes they are uncooperative.

What you do

  1. Checks the log: delivered but never opened
  2. Phones the switchboard and gets the replacement

What you get

The supplier delivers in two days; the person they were writing to had left in the spring.

The situation

The contact changes and notices keep going to their address.

What you do

  1. Updates the contact on the files

What you get

The notice reaches somebody who exists.

The situation

The new contact does not know what had been delivered.

What you do

  1. Shows them the file's status

What you get

They catch up without phoning anyone.

The situation

A new file is opened for the new person.

What you do

  1. Continues the existing one, changing the contact

What you get

No history is lost.

The situation

Nobody knows who replaces the previous contact.

What you do

  1. Asks the company before chasing

What you get

The request reaches somebody who can act.

The situation

The old contact keeps receiving information.

What you do

  1. Revokes their access on updating

What you get

Information stops going to somebody it should not.
