For the same budget, email often outperforms social media: you own the list, no algorithm sits in between, and the message actually arrives. But a purchased or poorly managed list kills deliverability.
You build it slowly, cleanly, and measure as you go.
01 — The list
Consent only
- A clear sign-up form, stating what subscribers will receive and how often.
- Never purchased or scraped addresses without consent.
- A useful lead magnet to give people a reason to subscribe.
02 — The tool
A dedicated sending service
An email tool handles deliverability, unsubscribes, and statistics. Sending a newsletter from a regular inbox ends up in spam, and can get your domain blacklisted.
03 — Deliverability
Three records to configure
SPF, DKIM and DMARC authenticate your sends with email providers. Without them, a share of your emails never arrives. See our guide on domain names and hosting.
04 — The content
Useful, regular, personal
- An editorial line: what the subscriber gets out of each issue.
- A sustainable pace (weekly, biweekly, monthly) — announced and kept.
- An honest, concrete subject line; the first send should be a welcome sequence.
05 — Measure
What actually matters
Open rate (subject line and reputation), click rate (content and offer), unsubscribe rate (relevance and frequency). Adjust based on these three numbers.

Frequently Asked Questions
How often should you send?
Whatever pace you can sustain while delivering value every time. One good email a month beats an empty one every week.
Is double opt-in mandatory?
Not everywhere, but it improves list quality and deliverability, and it secures consent.
What should you do about inactive subscribers?
Run a re-engagement campaign, then remove those who don't respond: they drag down your open rate and reputation.
