Troubleshooting

My emails are not arriving

Why they land in spam, and the three things that fix it for good.

Updated on 13/08/2026

If several different people say nothing arrives, it is neither coincidence nor bad luck: the recipient's mail system does not trust the sender. And trust is demonstrated, not requested.

The three things, by impact

  1. 1

    Use your domain

    Mail from @yourcompany.com passes filters a generic address does not. This changes the most.

  2. 2

    Authorise sending

    A few records have to be added to your domain saying this platform may send on your behalf. Whoever manages your domain does it in ten minutes.

  3. 3

    Mind the wording

    No capitals in the subject, no exclamation marks, no "URGENT". Filters read it literally.

Watch out

Until the domain is authorised, the mail arrives claiming to be from you without being able to prove it. Gmail and Outlook filters treat that as suspicious, and rightly so.

In the meantime

An SMS or WhatsApp arrives even when email does not. It is not the underlying fix, but it unblocks today's case.

How do I know if a particular email bounced?

The case flags it, with the reason.

Can I ask people to add me to their contacts?

Yes, and it helps, but it does not replace authorising the domain.

How long before the change shows?

A few hours after the records are in place.

A real case

The situation

An accountancy firm finds half its notices are never opened.

What you do

  1. Switches to their own domain
  2. Their IT person adds the authorisation records
  3. Rewrites subject lines without capitals

What you get

Open rates go from 40% to 85% in a week.

The situation

Notices land in junk at one particular client.

What you do

  1. Asks them to add the sender to their safe list

What you get

The next notice reaches the main inbox.

The situation

A send goes to an old list and many addresses bounce.

What you do

  1. Cleans the contacts before the next round

What you get

Sending reputation does not suffer.

The situation

A corporate domain blocks everything external.

What you do

  1. Agrees with their IT to allow the sender

What you get

The block is resolved once for the whole company.

The situation

The supplier says it never arrived and it shows as sent.

What you do

  1. Checks the send time and resends

What you get

You learn whether the problem is sending or receiving.

The situation

Subject lines that look like marketing are used.

What you do

  1. Writes specific subjects saying what is requested

What you get

The email gets opened rather than dismissed.
