Contacts and channels

When the contact has no email

Some people work from a phone alone, and it is not a rare exception: in some trades it is the majority.

Updated on 13/08/2026

The self-employed haulier, the installer working alone, the farmer, the small village supplier. They generally have an email address, but they do not look at it: their working tool is a phone, and there what works is a message. Treating them as if they had an inbox open all day guarantees no reply.

Which channel works with whom

SituationWhat works bestWhat to expect
Works in an officeEmailA reply within hours or by the next day
Works on the road or on siteA message to their phoneA fast reply or none
Has email but never checks itA message flagging it, email with the detailThey answer the message, not the email
You must be sure they read itMessage plus a short callThe least popular option and the most effective

Important

What almost nobody accounts for when moving to the phone: **what goes to a phone is read standing up, one-handed**. A message with three paragraphs, two links and a «please find attached» does not get read: it gets postponed. What works there is one sentence saying what is needed and one link, nothing else. The same request that fills half a screen by email has to fit in two lines on a phone — and that rewrite is the difference between getting the document today and chasing it for three weeks.

How to set it up without overcomplicating

  1. 1

    Note on the card where they actually receive things

    Not the channel they gave you: the one they reply from.

  2. 2

    One request per message

    On a phone, two requests together is one lost request.

  3. 3

    Make it possible to take a photo and send it

    It is all they will do, and it is enough if the photo is legible.

  4. 4

    And file whatever they send where it belongs

    Arriving by phone does not mean living on someone's phone.

Watch out

One case worth planning for before it happens: **the number you were given may be personal**. When that person leaves the company, they take the number, the history and the whole thread — and nothing of what was agreed remains with you if it all happened there. So whatever is agreed by message gets copied into the file the same day, even if the conversation carries on wherever suits them.

When there is genuinely no phone and no email

Worth knowing

Writing to someone through a new channel has its own rules — consent, hours, and their right to ask you to stop. That is covered separately, and applies to phones as much as to email.

Can I request documents over messaging?

Yes, and it often works better. What matters is where they end up filed.

What if they send a blurry photo?

Ask for a retake there and then: tomorrow they are no longer in front of the paper.

Is calling worth it?

For the important ones, yes. A one-minute call saves four reminders.
