Building a mailing list takes four parts: an email platform, a reason to join (a lead magnet), places to collect sign-ups, and a follow-up sequence that turns subscribers into buyers. Start with a free or low-cost email tool, authenticate your domain, create one strong free gift, and send a welcome sequence. Then email regularly with value and offers.
The four parts of a mailing list
| Part | What you need |
|---|---|
| Email platform | A tool with forms, automations and one-click unsubscribe |
| Lead magnet | A specific free gift your audience wants |
| Sign-up points | Opt-in page, site forms, social bio link, popups |
| Follow-up | A 3 to 5 email welcome sequence, then regular emails |

Rules to follow
- Only email people who opted in

Inbox rules: Gmail and Yahoo require bulk senders to authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe, and keep spam complaints under 0.3%.

Build three lists, not one
Strong email businesses build three lists: prospects (free opt-ins), customers (buyers) and partners (affiliates and joint-venture partners). Tag buyers automatically so they get different emails from prospects, and keep a separate list of partners for launches. Read more in the 3 email lists every online business needs.
Responsive beats big
A list is only an asset if it opens, clicks and buys. New subscribers are most interested the moment they join, so help them straight away, including a relevant recommendation in your first emails, rather than waiting weeks to make an offer.
