Email is the only audience you own. Social platforms change their reach overnight and search rankings move without warning, but a list of people who agreed to hear from you belongs to your business.
This guide covers starting from zero: what to offer, where to ask, and the consent rules that apply in the UK.
- 1
Decide what the list is for before collecting anyone
A list with no purpose never gets emailed, and a list that goes quiet for a year is worthless when you finally use it. Decide what you will send and how often — monthly tips, seasonal offers, project updates — before you ask anyone to join.
- 2
Offer something better than "sign up for updates"
Nobody wants updates. They want the pricing guide, the checklist, the maintenance calendar, the thing that solves a small problem now. It should take you an afternoon to produce and genuinely help — a thin download damages trust at the first contact.
- 3
Get the consent mechanics right
Under UK GDPR and PECR, consent must be freely given, specific and unambiguous. No pre-ticked boxes, no bundling consent with a purchase, and a clear statement of what they are signing up for. Record when and how each person consented — you may need to demonstrate it.
- 4
Put the form where intent is highest
At the end of useful content rather than in a sidebar nobody reads. Someone who has just read a guide to the end is at their most receptive. One well-placed form beats the same form repeated on every page.
- 5
Ask for as little as possible
Email address, and a first name only if you will genuinely use it. Every extra field reduces completion measurably. You can ask for more later, once they have a reason to trust you with it.
- 6
Send the first email immediately
Deliver what was promised straight away, automatically, and use it to set expectations: what you send and how often. The first email has by far the highest open rate you will ever get. Wasting it on a bare download link is a missed introduction.
- 7
Email consistently or not at all
A list emailed monthly stays warm. A list emailed once a year produces spam complaints, because nobody remembers signing up. If you cannot commit to a regular rhythm, do not build the list yet.
Legitimate interest and existing customers
There is a narrow exemption — often called the soft opt-in — allowing you to market similar products to people who bought from you, provided they were offered an opt-out at the point of sale and in every message. It does not extend to enquiries who never bought, and it does not cover buying a list.
What good looks like
For a small business list, open rates of twenty to forty per cent are healthy. Falling engagement usually means you are emailing too rarely rather than too often — people forget who you are.
Frequently asked questions
Only with their consent. The soft opt-in exemption applies to people who actually purchased, not to everyone who made contact. Ask at enquiry stage instead.
