Key takeaways
The common cold DM mistakes are pitching in the first message, sending obvious copy-paste templates, messaging people with no reason to hear from you and following up too often. A good first message is short, specific to the person and asks for nothing big. Marketing messages to individuals can also need consent under PECR.
- Never pitch in the first message.
- Mention something specific to the person.
- Ask a small question, not for a meeting.
- 1 polite follow-up is enough if there is no reply.

Chat on WhatsApp →Why do cold DMs fail?
Cold DMs fail because most read as automated sales messages from strangers. The person has no reason to trust you, the message is about you, and it asks for their time. Most people delete it, and some report it, which can limit your account.
What are the most common outreach mistakes?
The most common mistakes are easy to recognise from the other side of the inbox.
- A sales pitch straight after connecting.
- A template that names the wrong company.
- Long messages about your services.
- Asking for a call before any conversation.
- Three follow-ups in a week.
What does a good first message look like?
A good first message is two or three lines: why you are getting in touch with this person specifically, something useful or relevant, and a small question. For example, a comment on their recent post and a question about how they handle a common problem. Let them ask what you do.
Want message templates that sound like you? Message us on WhatsApp and we will discuss your requirements.
Chat on WhatsApp →What are the rules on messaging people?
Under the Privacy and Electronic Communications Regulations (PECR), marketing messages sent electronically to individuals generally need their consent, with limited exceptions. Rules for messaging corporate subscribers differ. Platform rules also limit unsolicited bulk messaging. Check ICO guidance before running any messaging campaign.
When is a direct message the right move?
A direct message is right when there is a genuine reason: they asked a question publicly, engaged with a relevant post, are a mutual contact, or you have something specific and useful to share. Warm messages to people who have shown interest work far better than cold ones.
How do you spot spammy outreach in your own messages?
Spot it by reading your last five outreach messages as the recipient. If they mention you more than the recipient, ask for a call, could be sent to anyone unchanged or follow up more than once in a week, they read as spam. Reply rates under one in ten are another sign.
- More about you than them.
- A request for a call in message one.
- Could be sent to anyone unchanged.
- Low reply rates.
What does this look like in practice?
A pattern we see: a business sending 50 identical LinkedIn pitches a week with almost no replies. Switching to five specific messages a week to people who engaged with a post brings fewer messages and more conversations.
Outreach checklist
- Have a genuine reason to message.
- Mention something specific.
- Keep it to two or three lines.
- Ask a small question, not for a meeting.
- Follow up once, then stop.
Next step
Read your last cold message as if you received it. If it is mostly about you, rewrite it around the other person.

Frequently asked questions
Is it OK for a business to send cold DMs?
It can be, if messages are specific, relevant and not a pitch, and you respect platform rules and PECR. Bulk, copy-paste sales messages tend to be ignored or reported and can limit your account.
What should I say in a first message to a prospect?
Two or three lines: why you are contacting them specifically, something relevant or useful, and a small question. Avoid pitching or asking for a call in the first message.
How many times should I follow up a DM?
Once, after about a week, if there was no reply. More than that tends to annoy people. If they do not reply, engage with their posts instead and leave the door open.
