Email Marketing Guide for Beginners

Why email still works

Social reach depends on an algorithm; an inbox does not. If someone gives you their address, you can reach them directly, repeatedly, at almost no marginal cost. The trade-off is permission: the moment you send things people did not ask for, they unsubscribe or mark you as spam, and deliverability suffers for everyone on your list.

1. Build the list honestly

• Collect addresses with explicit consent and say what you will send and how often.
• Offer a reason to subscribe: a useful guide, a discount, order updates, early access.
• Use double opt-in where your audience or jurisdiction expects it — smaller list, better engagement.
• Never buy or scrape lists. It damages deliverability and, in many countries, breaks the law.
• Include a visible unsubscribe link in every send and honour it immediately.

2. Segmentation

Sending everything to everyone is the fastest way to train people to ignore you. Useful starting segments:

3. Subject lines and preview text

• Aim for roughly 30–50 characters so mobile clients do not truncate.
• Be specific rather than clever: "Your April invoice summary" beats "Big news inside".
• Use the preview text as a second line of copy, not a repeat of the subject.
• Avoid ALL CAPS, rows of emoji and false urgency — they trigger filters and distrust.
• Never promise something the email does not deliver.

4. The welcome sequence

The first few days after signup are when interest is highest. A simple three-email sequence works for most businesses:

• Email 1 (immediately) — deliver what was promised, set expectations, one link.
• Email 2 (day 2–3) — your most useful piece of content; teach something.
• Email 3 (day 5–7) — how you help, with proof, and a single clear next step.

5. Promotional emails

• One offer, one call to action, repeated two or three times in the email.
• State the terms plainly: price, deadline, who it applies to.
• Lead with the benefit; put the details underneath for people who want them.
• Keep promotional sends to a minority of your calendar so the list stays warm.

6. Personalisation that is not creepy

• First name in the body is fine; a fake "I was just thinking about you" is not.
• Personalise by behaviour — what they bought, viewed or downloaded — rather than by guesswork.
• Always set a fallback for missing merge fields ("there", not "Hi ,").

7. Calls to action

• One primary action per email. Secondary links compete with it.
• Button text describes the outcome: "Book a call", "See the sizes", "Download the checklist".
• Place the CTA above the fold and repeat it at the end.
• Make sure the landing page matches the email's promise.

8. Testing

• Test one variable at a time — subject line, or CTA, not both.
• Give the test a large enough segment and a defined window before deciding.
• Send yourself a preview and check it on a phone, in dark mode, with images blocked.
• Verify every link before the send goes out.

9. The numbers worth watching

Authenticate your sending domain (SPF, DKIM and DMARC) and clean hard bounces regularly. Good deliverability is invisible when it works and impossible to ignore when it breaks.
