Email 1 — sent immediately: deliver the promise
Whatever got them to sign up — a discount code, a lead magnet, "join the list" — hand it over here, with no delay and no extra ask. Subject line example: "Here's your 15% off code (and welcome)." This email's only job is to keep the promise. Don't try to sell anything else in it.
Email 2 — day 2: set expectations
Tell them what they actually signed up for — how often you'll email, what kind of content to expect, and one thing that makes you different from the fifty other brands in their inbox. This is also where you can ask a light, low-friction question ("what brought you here today?") to start segmenting engaged subscribers from passive ones.
Email 3 — day 4: prove it with a real story or result
This is the credibility email — a customer story, a specific result, a before-and-after. Not "we're the best," but a concrete example the reader can picture. If you're a service business, this is your best case study. If you're ecommerce, this is your strongest review with specifics attached.
Email 4 — day 7: one easy win
Give something useful with no ask attached — a tip, a mini-guide, a small discount that requires nothing but clicking. This email builds goodwill and reactivates anyone who opened emails 1–3 but hasn't clicked yet.
Email 5 — day 10: the real invitation
Only now, once trust has actually been built, make your strongest ask — the main product, the higher-value offer, the booked call. Rushing to this on day one is why so many welcome sequences underperform: the ask arrives before the trust that makes someone say yes.
What breaks a welcome sequence
Sending all five emails in two days feels desperate. Sending them a week apart with nothing but silence for days loses momentum. And skipping straight to a hard sell in email one — before you've delivered anything or earned any trust — is the single most common reason welcome sequences underperform.
