Introduction

A welcome series is the sequence of emails a new subscriber receives after signing up. It is not a single automated email. It is your only chance to set expectations, build a relationship, and train the inbox to actually show your future emails. Most newsletter creators focus on growing their list and then neglect what happens immediately after someone subscribes. That is a mistake. A well-built welcome series can be the difference between a subscriber who opens every email and one who never sees your newsletter again.
You can build your welcome series directly in LetterBucket from Subscribers → Welcome Email.

​
How many emails should a welcome series have?

Three emails is the optimal number for most newsletters.
  • One email is too little. It forces you to cram too much into a single message, and it leaves too much to chance. If that first email lands in Promotions or Spam, you lose the subscriber forever.
  • More than five emails often feels like a course or a heavy commitment. Most people sign up for a newsletter expecting it to be simple. A seven-email welcome series can feel overwhelming before they have even read a single edition.
  • Three emails hits the sweet spot. It gives you enough space to do three essential things: secure inbox placement, set expectations, and deliver value. It feels intentional but not demanding.
A two-email series can work for very simple newsletters where the value is immediately obvious. A five-email series can work if you are teaching something step by step. But for the vast majority of creators, three emails is the right starting point.

​
Email 1 — Secure inbox placement

When to send: Immediately after signup. Purpose: Confirm the subscription and secure future inbox placement. The person is still engaged, their attention is on you, and they are expecting something from you. Do not waste that window.

​
What to include

  • A clear thank you
  • A simple request to check where the email landed (Inbox, Promotions, Spam)
  • A request to move it to the main inbox if it did not land there
  • A request to save your email address as a contact, or reply with a simple word like “okay”
  • A preview of what comes next

​
Why it matters

Email providers learn from what subscribers do. When someone moves an email from Promotions to Inbox, that signal matters. When someone replies — even with a single word — it tells the email provider that this is a wanted, engaged relationship. These small actions in the first email dramatically increase the chance that future emails land where they should. Skip this, and you risk losing a percentage of your subscribers before they ever see your second email.
Do not ask for too much. Asking someone to reply, move the email, and add you as a contact all at once can feel like a chore. Pick one or two actions and keep it light. Do not send them to a long survey or a sales page — the first email is about establishing the connection.

​
Example

Subject: One quick thing (please read)

Hi [Name],

Thanks for signing up for The Weekend Reading.

Before I send your first issue, I need to ask one small favor.

This email may have landed in your Promotions folder or Spam. If it did,
please drag it to your main Inbox. If you are on Gmail, you can also reply
to this email with "okay" — that tells Gmail we know each other.

I am asking because I want to make sure my future emails actually reach you.

Your first full newsletter will arrive tomorrow. It is a short one, I promise.

Thanks again,
Alex

​
Email 2 — Set expectations

When to send: One day after Email 1. Purpose: Welcome them to the newsletter and explain what they signed up for.

​
What to include

  • A welcome to the actual newsletter
  • A brief explanation of what you send, how often, and what someone can expect
  • A taste of what makes your newsletter different
  • A clear link to the last issue or a “best of” page
  • A simple call to action that invites engagement

​
Why it matters

Subscribers need to know what they signed up for. Many people subscribe on impulse and then forget why. This email anchors them. It answers the unspoken questions: How often will I hear from you? What kind of content is this? What is in it for me? When you set clear expectations, people stay subscribed longer. When you leave it vague, they unsubscribe at the first email that does not match their assumption.
Do not make this email about you. Do not share your origin story unless it directly explains what the newsletter does. Focus on the subscriber. Avoid vague phrases like “exclusive content” or “valuable insights” — be specific about what you actually send. Asking them to buy something in email two usually backfires. Build trust first.

​
Example

Subject: Welcome to The Weekend Reading

Hi [Name],

Welcome to the actual newsletter.

Here is what you signed up for: every Friday morning, I send one article,
one book recommendation, and one small creative prompt. No fluff. No spam.
Just three things to start your weekend.

You can expect it in your inbox between 8 and 9 AM.

If you want to get a feel for what these look like, here is last week's issue:
[Link to last issue]

I also have a "best of" page if you want to browse past favorites:
[Link to best of page]

If you have any questions about what I send or why, just reply.
I read every response.

See you Friday,
Alex

​
Email 3 — Deliver value

When to send: Two to three days after Email 2. Purpose: Give them something useful and invite a deeper connection. Do not wait a full week. The welcome series should feel like its own short experience, not just a preview of the regular cadence.

​
What to include

  • A piece of value that stands on its own (a short guide, a resource, a recommendation, a useful tip)
  • A simple invitation to reply or engage
  • A brief reminder of what comes next (the regular newsletter schedule)
  • A low-pressure invitation to share the newsletter if they find value

​
Why it matters

The third email is where you demonstrate why someone should stay subscribed. The first email was about delivery. The second was about expectations. The third is about value. If you only tell people what you do but never show them something useful, they will not stick around. This email gives them something tangible. It also creates a final touchpoint before the regular schedule begins, reinforcing that you are a real person on the other side.
Do not make this email purely promotional. Even if you sell something, lead with value first. Avoid a generic “thanks for subscribing” message — that wastes the opportunity. Give something real, not a preview or a tease.

​
Example

Subject: One resource to get you started

Hi [Name],

I want to leave you with one thing before your first regular issue arrives on Friday.

One of the most common questions I get is how to find time to read more.
So I put together a short list of the five ways I make reading a consistent habit.

It is short. You can read it in three minutes.
[Link to the resource]

If you find it useful, feel free to forward it to a friend who might like it.
Or just reply and let me know what you think.

Otherwise, I will see you in your inbox Friday morning with your first full issue.

Thanks for giving this newsletter a shot,
Alex

​
Common mistakes

Many creators go straight to “welcome to my newsletter” without ever asking the subscriber to train the inbox. That leads to lower open rates for every email that follows.
Five or six emails before the first regular issue feels like a commitment. People unsubscribe because they feel overwhelmed before they have even seen what you normally send.
If you never say how often you email, subscribers will guess. When they guess wrong, they mark you as spam or unsubscribe.
A welcome series is not a launch sequence. It is an onboarding experience. If you try to sell something in the second email, you look like you only care about the transaction.
If someone signed up for a specific lead magnet, your welcome series should acknowledge that. A generic series for all subscribers misses the chance to connect on the specific thing they wanted.
