Welcome email sequences: what to send in the first five days

What a welcome email sequence is

A welcome email sequence is a fixed, ordered set of emails delivered automatically to each new subscriber, beginning when they confirm their address rather than on a date you choose. It is written once. From then on every person who joins receives the same emails, in the same order, counted from their own first day, which is why one subscriber can be on email two while another is on email five.

That is the whole mechanism, and it is worth separating from two things it is often confused with. It is not the confirmation email: that message exists to get a click that proves the address belongs to the person who typed it, and it should contain almost nothing else. Nor is it a newsletter: a newsletter goes to everybody at once and is written again every week.

The job of the sequence is narrower than it sounds. A stranger has just traded an email address for something, and in about a week they will have forgotten the exchange unless you give them a reason not to. The sequence turns an address into a reader who recognises your name in a From line. Everything below is in service of that one outcome.

Why the first days carry the most attention you will ever get

Three things are true on the day somebody signs up and get less true every day afterwards. They remember deciding. They remember what they were promised. And they are expecting mail from you, which means your message arrives as something that was asked for rather than as an interruption. No subject line you write in month six competes with that.

The published benchmark reports from the large sending platforms consistently show welcome messages opening at roughly two to three times the rate of an ordinary campaign to the same list, and the direction of that gap is more reliable than its size, because the size depends on how each report counts an open. Treat it as a structural advantage rather than a number to hit: the reader is warm, and the only question is whether you send anything into that window.

There is a second reason to load the first week, and it is technical. The large mailbox providers decide where your mail lands partly from how the people who receive it behave, and a new subscriber who opens, clicks and occasionally replies is the best evidence you will ever generate. Google asks bulk senders to keep the spam-complaint rate reported in Postmaster Tools below 0.10 per cent and never to reach 0.30 per cent, and complaints cluster where mail is unexpected. A first email that arrives three weeks after sign-up is mail from a stranger about a form the reader no longer remembers filling in, and it is reported at a rate that has nothing to do with how good the writing is.

A welcome sequence and an email course are not the same thing

They share their machinery. Both are finite, both are written once, both are delivered automatically from each subscriber’s own start date, and both are usually a handful of emails on consecutive mornings. What differs is what the reader was promised at the form, and that difference decides the content.

An email course promises an outcome: by Friday you will be able to do a specific thing. Its five emails are the steps to that outcome, and the reader judges it by whether they can do the thing. A welcome sequence promises a relationship: you will hear from me. Its emails introduce a person, a point of view and a body of work, and the reader judges it by whether they now want the next email.

The practical consequence is that a course is a much better thing to offer on a sign-up form, because the ask is legible before it is accepted, while a welcome sequence is what has to run when the offer was the list itself. If your opt-in offer is a course, the course is your welcome sequence and you should not also run one: two automated series arriving at one new subscriber on the same five mornings is two emails a day from somebody they have not met. A course as the door in and a welcome sequence for people who arrived by some other route is the arrangement that works.

The five emails, and what each one is for

Five is a working week: short enough to write in one sitting, long enough for your name to become familiar. The five jobs below are in this order because each one is only credible once the one before it has landed.

Notice that the ask is last and that there is exactly one of it. A sequence with a different call to action in every email reads as a sales funnel wearing a welcome as a costume, and the reader is right to read it that way. One ask, made once, to somebody who has had four useful mornings, converts better than four asks made to somebody who has had none.

The five jobs, one per morning:

• Email one, deliver the promise. Whatever the form said they would get, they get it here, above the fold, in the first screen, with no preamble. If it is a file, the link is the first thing in the email. If it is the first lesson, the lesson starts in line one. Nothing else belongs in this email, and in particular no ask.
• Email two, the story. Who you are, what you work on, and why you work on this in particular. Two hundred to four hundred words, specific and small: one decision you made, one thing that went wrong, one thing you learned from it. This is the email that makes the next three sound like a person rather than a channel.
• Email three, the one belief. The single thing you think about this subject that most people in it get wrong. This is the most important email in the sequence, because it is the one that tells a reader whether your advice will be different from the advice they have already ignored. State it plainly, then earn it in one page.
• Email four, the proof. The belief from email three, working. A case, a before and after, a number with its basis, a piece of your own work you can show. Not a testimonial wall: one thing, in enough detail that it could not have been invented.
• Email five, the ask. What you would like them to do now, once, clearly, with the reason it follows from the four emails before it. Buy the thing, book the call, reply with a question, join the paid list. Then say what arrives from here on and how often, so the reader knows what they are keeping.

The sequence on one page

The table below is the plan rather than a template. What matters in the calls to action is that there is one per email and that none of the five is a cliffhanger, because a reader who feels handled on Tuesday is gone on Wednesday.

Timing: one a day, in the morning, in the reader’s own time

One email a day is the cadence that does the most work, because the point of a sequence is rhythm. An email every third day covers the same ground in a fortnight, by which time each one has to re-introduce itself. Daily removes that cost: by Thursday, your From line is something the reader has seen three times this week.

Pick one hour, somewhere between six and nine in the morning, and hold it for all five days. The hour matters much less than the consistency, because what you are building is an expectation: the fourth email should arrive where the reader learned to expect the third. Moving it around throws away the only compounding effect a five-day sequence has.

Send that hour in the reader’s own timezone rather than yours. A sequence sent at eight in the morning Central European Time reaches a reader in California at eleven at night, which is the worst slot in the day for anything that wants to be read and acted on. If you collect a timezone at sign-up, use it; if you can only infer it from where the confirmation click came from, that is still better than one global hour; and if you can do neither, choose the hour that suits the largest part of your list and accept that the rest are reading in the evening.

Do not skip weekends. A five-email sequence that only sends on working days takes nine calendar days to finish, and the gap between email three on Friday and email four on Monday is where completion falls. For business-to-business subjects the counter-argument is real, and the honest fix there is to start the sequence on a Monday rather than to put holes in it.

Day one starts after confirmation, not after the form. The confirmation click is the moment the address is proven and the moment the reader is most engaged. An unconfirmed address should receive exactly one message, ever: the request to confirm.

When one welcome email is the right answer

A single welcome email is much better than nothing, and it is genuinely the right choice in two situations. The first is that your opt-in offer was one self-contained thing, a file or a discount code, and there is no honest second email. The second is that you do not yet know what you would say on days two to five. A sequence of five emails where two of them exist to fill a slot is worse than one email that does its job, because the empty ones teach the reader to skip you.

What one email costs you is the familiarity, and the second chance at the ask. A reader who has seen your name once has not formed a habit, and in a single email you must either make your offer immediately, to somebody who has had nothing from you yet, or not make it at all.

The useful middle is a short sequence. Three emails you believe in beats five where the middle sags. Write the ones you have, ship them, and add the fourth and fifth when you have something to put in them: every subscriber who joins after you extend it gets the longer version.

What to do when somebody joins in the middle of a launch

Here is the collision. You are sending four broadcast emails to the whole list this week because something is on sale, and on Wednesday morning a stranger confirms their address. The automated sequence sends them email one. The launch sends them the third message of a campaign whose first two they never saw. They now have two emails from you in a day, one of which refers to a deadline they have no context for, and their honest reading of the situation is that they made a mistake on Tuesday.

The fix is a rule about how much mail one person can receive from you in a day, and the rule should be one. Everything else follows from it. In practice that means excluding recent joiners from broadcast campaigns until their sequence has finished, which most sending tools express as a filter on how long ago somebody subscribed: exclude anyone who joined within the last six days, which is the length of the sequence plus one.

The alternative, pausing the welcome sequence for the duration of the launch, is the more common choice and the worse one. It spends the highest-attention days a subscriber will ever have on a campaign written for people who already know you. If a new subscriber has to miss something, let them miss the launch. They will see the next one, and they will see it as somebody who has read five of your emails.

What to measure, and what usually goes wrong

Measure four things per email and one thing overall. Per email: the click rate on the single call to action, the unsubscribe rate, the complaint rate, and the number of replies, which is the least fashionable and most informative of the four. Overall: completion, the share of people who receive email five, which on a confirmed list usually sits between two thirds and nine tenths depending on how aggressively your provider suppresses bounces.

Treat open rates as a direction rather than a measurement. Several large mail clients now load tracking images by default for every message, whether or not anybody read it, so an open number is inflated by an amount you cannot see and which differs by audience. The click on the one call to action is the smallest honest signal you have; a reply is the strongest.

Read the unsubscribe rate per email rather than as a total. A total tells you people left. The per-email figure tells you which email they left after, and that email is almost always the one that broke the promise made at the form: an ask that arrived before anything was delivered, a story with no point, or a Tuesday email about something the reader did not sign up for. The same applies to complaints, with a lower tolerance, because the thresholds Google publishes are absolute rather than relative.

The mistakes that come up most often, in rough order of how much they cost:

• Nothing arrives for a fortnight, and then the first email lands as mail from a stranger. This is the expensive one, and it is a scheduling decision rather than a writing problem.
• Email one is about the sequence rather than the thing that was promised. A reader who has to scroll to find what they signed up for has already learned something about how you treat their attention.
• An ask in every email. Five different calls to action in five days is a funnel, and readers recognise the shape long before they can name it.
• A sender name or address that does not match what the form said. The reader agreed to hear from a person or a publication, and mail from something else is indistinguishable from a list that was sold.
• No working unsubscribe in every message, including the automated ones. One-click unsubscribe is what the large providers now ask of bulk senders, and it has a specification: a List-Unsubscribe-Post header and a URL that acts on a POST and returns a plain success.
