Welcome email best practices: how to write one that gets read

What a welcome email is for#

A welcome email is the first message someone gets after they give you their address: signing up for a newsletter, creating an account, or ticking a box at checkout. It has three jobs, in this order. It confirms the address works and the person meant to sign up. It tells them what they will get from you and how often. And it gives them one useful thing to do next.

Those jobs are not a copywriter’s invention. M3AAWG, the industry body where senders and mailbox providers write best practices together, says a notification should go out “immediately following an end user submitting their address to a list or as soon as possible (within 24 hours)”, should include the address that was submitted, should state “the frequency and type of content of the mailings”, and should “use the same ‘from’ address as future messages”.^[1] Yahoo’s sender guidance asks for the same thing in plainer words: “Let them know what mail to expect, how often it will be sent, and what it will look like.”^[2]

Why the welcome email matters: what benchmarks show#

Welcome emails consistently do better than ordinary campaigns in the benchmarks email platforms publish from their customers’ sends. Two recent ones, with very different absolute numbers:

Apple’s own announcement says the feature “helps users prevent senders from knowing when they open an email”.^[6] So judge a welcome email by clicks, replies, activations and purchases, not by opens. The companion guide, how to clean your email list and sunset inactive subscribers, explains what this does to any rule built on the last open date.

Welcome email best practices, one by one#

Ranked roughly by how much evidence stands behind each. The first four are what mailbox providers and M3AAWG ask for; the rest are editorial judgement, and we say so.

1. Send it immediately, from an automation#

M3AAWG’s window is “immediately … or as soon as possible (within 24 hours)”.^[1] In practice that means an automation triggered by the signup itself, not a weekly batch. The subscriber has just given you their address; a message that arrives while they still remember doing so is recognised, and a message that arrives a week later is more likely to be mistaken for spam.

2. Confirm the address before you market to it#

Google’s sender guidelines say: “Make sure recipients opt in to get messages from you. Confirm each recipient’s email address before subscribing them.”^[7] Yahoo recommends the same click-to-confirm step.^[2] M3AAWG calls confirmed opt-in “the highest standard” because it “prevents a typo or a maliciously submitted address from being added to ongoing mailings”.^[1] A welcome email sent to a mistyped address bounces or, worse, reaches a stranger who reports it.

3. Send it from the address future mail will come from#

M3AAWG asks for the same From address as future messages “so recipients may add it to their address book”,^[1] and Google asks that “messages of the same category should have the same From: email address”.^[7] If the welcome comes from news@example.com, the newsletter should too. If you also want readers to move you out of Gmail’s Promotions tab, the welcome email is the one place to ask; the Gmail Promotions tab guide explains how, and why asking once beats asking every issue.

4. Say what they will get, and how often#

This is the one part of the content that M3AAWG and Yahoo both specify. M3AAWG adds a warning: “Unexpected increases in the frequency of messages often leads to increased abuse complaints.”^[1] Write the promise concretely (“one email every Tuesday with the week’s changelog”), then keep it. If people can choose topics or frequency, link to that choice here.

5. Give it one job and one main link#

Unproven This is editorial advice, not a measured rule: a welcome email that asks for one thing (finish setup, read the best article, use the discount) makes the next step obvious. A welcome email that also links your blog, five social profiles and three products makes the reader choose, and no step is the easiest choice. Secondary links are fine in the footer.

6. Deliver what the signup form promised#

If the form offered a discount code, a download or a free trial, put it in the first email, near the top. M3AAWG’s principle is that addresses “should only be used for the purposes disclosed to recipients at the time of signup”,^[1] and the natural reading is that the welcome email should deliver that purpose first and sell second.

7. Make leaving as easy as joining#

An unsubscribe link in a welcome email feels premature, but a new subscriber who cannot find one reports the message as spam instead, and Google asks bulk senders to keep the spam rate below 0.10% and never reach 0.30%.^[7] A marketing welcome email from a bulk sender must support one-click unsubscribe and show a visible link in the body.^[7] Omnisend’s data shows new subscribers do leave: welcome emails had a 0.87% unsubscribe rate, among the highest of the automations it measured.^[4] An unsubscribe at this point is cheap; a complaint is not.

Welcome email subject lines and preheaders#

The subject line and the preheader (also called preview text) are what a reader sees before deciding to open. For a welcome email, the job of both is recognition: the reader should connect the message to the form they just filled in.

• Name the thing they signed up for. “Welcome to the Acme changelog” is recognised; “You won’t believe what’s inside” looks like the mail they did not ask for.
• Deliver the promise in the subject if there is one. “Your 10% code is inside” tells the reader the email is the thing they were waiting for.
• Use the preheader to add, not repeat. If you do not set one, Litmus notes that clients fill the space from the first lines of the email, which can be an image’s alt text or an unsubscribe line.^[8]
• Keep the preheader short. Litmus recommends “keeping the preview text under 90 characters”, because readers’ settings can show anywhere from about 278 characters to none.^[8]
• Keep the subject honest. In the United States, CAN-SPAM forbids deceptive subject lines, and the FTC judges a mixed message’s primary purpose partly by what a reader would conclude from its subject line.^[9]

A sample welcome sequence (an example, not a formula)#

One email can do the three jobs. A short series lets each email do one. The sequence below is an example we wrote for a software product with a newsletter; nobody has shown that three emails beat two or five, so fit the length to how much a new subscriber really needs to know.

Two rules keep a sequence from turning into a pile-on. Stop it the moment the person does the thing it is asking for, so nobody is told to finish a setup they have finished. And start the regular newsletter only after the sequence ends, so a new subscriber does not get three emails in a day.

What the first email can look like#

An example, written for this guide, of a first email that does all three jobs in under a hundred words:

From:      Acme Changelog <news@acme.example>
Subject:   Welcome to the Acme changelog
Preheader: One email every Tuesday. Here's this week's.

Hi Maya,

Thanks for subscribing with maya@example.com.

Every Tuesday you'll get one short email: what shipped in Acme
that week and one tip for using it. Nothing else, and never more
than once a week.

Start here: the five features most teams set up first
https://acme.example/start

Reply to this email if you have a question — a person reads it.

Acme, 1 Example Street, Springfield
Unsubscribe: https://acme.example/u/7f3a9c

Each line maps to a practice above: the submitted address (M3AAWG), the frequency and content promise (M3AAWG and Yahoo), one main link, a postal address and an unsubscribe link (CAN-SPAM). For the variables in Hi Maya, see email template variables.

Step by step: build a welcome email that gets read#

The order matters: the first three steps decide whether the email arrives and is recognised, and the rest decide whether it is useful.

1. 1

   Trigger it from the signup itself

   Send the welcome email from an automation that starts when someone signs up, so it arrives within minutes. M3AAWG's guidance is immediately, and at the latest within 24 hours.

2. 2

   Confirm the address

   Use double opt-in, or at least show the submitted address back in the welcome email. Google and Yahoo both ask senders to confirm addresses, and it keeps typos and fake signups off your list.

3. 3

   Send from your regular From address

   Use the same From address that later messages of the same kind will use, so subscribers recognise you and can add you to their contacts.

4. 4

   Write the promise and one next step

   Say in one sentence what subscribers will get and how often, deliver anything the signup form offered near the top, and give the email one main link.

5. 5

   Write the subject line and preheader

   Name what they signed up for in the subject line, and set a preheader under 90 characters that adds information instead of repeating the subject.

6. 6

   Add the unsubscribe and legal lines, then measure

   Include a visible unsubscribe link, one-click unsubscribe headers for marketing mail and a postal address, then judge the email by clicks, completed actions and complaints rather than opens.

Building a welcome email in Rasket#

In Rasket the welcome email is an automation. Its trigger can be a contact being created, a contact subscribing to a topic, or a custom event your own product fires, such as user.signed_up. A send step sends a published template; a delay step waits; a condition step branches on the contact’s fields or topics, so the second email in the example sequence can go only to people whose setup_complete property is still false. See Automations.

The dashboard’s starter gallery includes a Welcome template, which you can edit in the drag-and-drop editor with your brand kit, and templates take variables such as {{first_name}}. See Templates. Emails sent by an automation behave like any other send: suppressions, quotas, unsubscribe headers and delivery events all apply, and each run shows what happened to one contact. For welcome mail that is purely about an account (the login link, the workspace URL), keep it on its own transactional address; the difference is set out in transactional vs marketing email.

How to measure a welcome email#

Pick the number that matches the email’s one job, and ignore the rest:

1. The action it asks for. Setup finished, first purchase, first article read. This is the only number that says the email worked.
2. Clicks on the main link. A click is a person acting. Apple describes Mail Privacy Protection as downloading an email’s remote content in the background, the images an open pixel hides in, not as following its links.^[10]
3. Complaints and unsubscribes. A rising complaint rate on the welcome email means people do not recognise it or did not mean to sign up; look at the signup form, not the copy.
4. Bounces. Hard bounces on welcome mail point to typos or fake signups, which confirmed opt-in stops.

Open tracking still has a use: a sudden drop in opens across all clients can show a delivery problem. It is no longer a measure of whether people read.

Welcome email myths and facts#

• Measured in research “Welcome emails outperform campaigns.” Fact, in every benchmark we opened: higher opens, clicks and conversions than regular campaigns.^[3][4]
• Measured in research “An 80% open rate means 80% read it.” Myth. Apple’s Mail Privacy Protection loads images whether or not the reader engages, and Apple clients account for most tracked opens.^[10][5]
• Unproven “The ideal welcome series is five emails.” No published study shows an ideal length. Stop when the reader has what they need.
• Unproven “Leave the unsubscribe link out of the welcome.” Unwise and, for most marketing mail, not allowed: CAN-SPAM and PECR both require an opt-out in the message.^[9][11]
• Documented by Google “Confirming the address costs you subscribers for nothing.” It costs the ones who never confirm. Google’s guidelines ask for confirmation anyway, because unconfirmed addresses bring bounces and complaints.^[7]

The rules that apply to welcome emails#

A welcome email is usually marketing, so marketing law applies to it. In the United States, the FTC decides by primary purpose: a message whose subject line suggests a promotion, or whose transactional content does not come mainly at the beginning, is commercial.^[9] Commercial email needs a valid postal address and an opt-out honoured within 10 business days, with penalties of up to $53,088 per violating email.^[9] In the UK, PECR means you “normally must have consent before sending unsolicited electronic mail marketing to individual subscribers”, and every message must give the recipient a way to opt out.^[11] Neither law exempts the first email.
