Direct mail to new companies: what the rules say

Marketing by post is not regulated by PECR, so you do not need prior consent for a letter. If you address it to a named individual, such as a director, UK GDPR still applies. Post is why it is a popular first contact for brand-new companies.

What this means in practice

• You do not need opt-in consent to post a business letter to a company.
• If the envelope carries a person's name, you are processing personal data. You need a lawful basis (usually legitimate interests) and you must be able to explain it.
• Addressing the letter to the company or a job title, such as "The Directors", involves less personal data than naming someone.

Do these things

1. Be clear who you are. Put your name, address and contact details on the letter.
2. Say where you got their details. Mention that you found the company in public records such as Companies House.
3. Give an easy way to opt out. A phone number, email or reply slip works. Honour it.
4. Keep a suppression list of anyone who objects, and check it before each mailing.
5. Be relevant. Write about something that helps a new business.

Using NewcoHunter for mailings

Every company has a registered address and named directors. A filter lets you keep only companies you can reach by post, and exports include a column for the person to address. See reachable by post and send a mailing.

A registered office is sometimes an accountant's or formation agent's address, so a letter may not reach the director. That is a delivery matter rather than a legal one.
