Phase 0 — Foundations

Before you send anything

Choose your email marketing platform
Pick based on list size and budget, not brand fame. If you're starting from zero, compare the cheapest options and the beginner-friendly picks before committing — switching later is a migration project.

Authenticate your sending domain (SPF, DKIM, DMARC)
This is the single most skipped step and the most common reason new senders land in spam. Set up SPF and DKIM before your first campaign, and publish a DMARC record. It takes under an hour and protects every email you'll ever send.

Import your list — with permission only
Only import contacts who agreed to hear from you. Never buy lists: they destroy deliverability, violate spam law in most countries, and the engagement is worthless. If your list is old, plan a re-permission email before regular sending.
Put a signup form on your website
One visible form beats three hidden ones. Homepage or footer placement, a clear statement of what subscribers get and how often. Every list grows or shrinks — make sure yours has an intake.

Phase 1 — First sends

Weeks 1–2

Send a welcome email
The first email a subscriber gets should arrive within minutes of signup: who you are, what they'll receive, and one useful thing. Welcome emails get the highest open rates you'll ever see — don't waste them on a bare 'thanks for subscribing'.
Send your first newsletter or broadcast
Keep it simple: one topic, one clear call to action. The goal isn't perfection, it's establishing the habit — for you and for your readers.
Pick a sending cadence you can sustain
Consistency beats frequency. A monthly email you actually send outperforms a weekly one you abandon by March. Start conservative; you can always send more to your most engaged readers later.

Months 2–3

Create your first three segments
New subscribers (first 30 days), engaged readers (opened recently), and inactive ones (quiet for 6+ months). You don't need twenty segments — three that you actually write differently for will beat a blast every time.

Set up one simple automation
A short welcome sequence for new subscribers: 2–3 emails over the first week. It's the highest-return automation in small business email and it runs itself once built.

Months 3–6

Add revenue automations (if you sell online)
Abandoned-cart reminders and post-purchase follow-ups. These emails send themselves and convert at multiples of broadcast rates — this is where email starts paying for the platform.

Re-engage or release your inactive subscribers
Send your quiet segment one honest 'still want these?' email. Keep the responders, suppress the rest. Pruning feels like losing audience; mechanically it raises your inbox placement for everyone who remains.

Ongoing

A/B test one thing per send
Subject lines first — they're the highest-leverage variable and the easiest to test. One test per email, keep a log of what won, and let the pattern compound.
Do monthly list hygiene
Remove hard bounces, process unsubscribes promptly, and keep an eye on the inactive segment. A clean list is a deliverable list.
Review deliverability quarterly
Check your spam complaint rate (keep it under 0.1%), confirm SPF/DKIM/DMARC still pass, and look at engagement trends by segment. Catching a slow decline early is cheap; recovering a damaged sender reputation is not.
