Customer onboarding is the process that guides a new customer from the moment they sign up or buy until they get their first result with your product or service.<\/strong> Its goal is to get them using it early and to keep them from dropping out in the first few weeks.<\/p>\n\n

The term comes from the phrase on board<\/em>. It is also known as customer welcoming or new customer integration.<\/p>\n\n

Email is the channel most commonly used for it. It arrives at the right moment, it can be automated and it shows which steps each customer takes.<\/p>\n\n

How is it different from a welcome email?<\/h2>\n\n

The welcome email<\/a> is a single message sent right after signup. Onboarding is a sequence of several emails with a specific goal: getting the customer to actually use what they have signed up for.<\/p>\n\n

<\/th>Welcome email<\/th>Customer onboarding<\/th><\/tr><\/thead>
What it is<\/td>One email<\/td>A sequence of emails and actions<\/td><\/tr>
When<\/td>Right after signup<\/td>First few days or weeks<\/td><\/tr>
Goal<\/td>Say hello and share the first details<\/td>Help the customer get value<\/td><\/tr>
Adapts<\/td>The same for everyone<\/td>Based on what each customer does<\/td><\/tr><\/tbody><\/table><\/figure>\n\n

It should also not be confused with employee onboarding, which is how a company welcomes a new hire. We cover it in our post on employer branding<\/a>.<\/p>\n\n

Stages of customer onboarding<\/h2>\n\n

1. Signup.<\/strong> The customer signs up or makes a purchase. They receive the confirmation and the welcome message.<\/p>\n\n

2. First steps.<\/strong> They set up their account or prepare what they need. Many customers are lost here if nobody guides them.<\/p>\n\n

3. Activation.<\/strong> They get their first result: they send their first campaign, use the product for the first time or receive the service. This is the most important moment.<\/p>\n\n

4. Adoption.<\/strong> They start using other features or buying again.<\/p>\n\n

5. Renewal.<\/strong> They pay again, upgrade their plan or recommend your brand.<\/p>\n\n

\"Stages<\/figure>\n\n

Which emails should you send during onboarding?<\/h2>\n\n

A simple sequence for the first few days:<\/p>\n\n

When<\/th>Email<\/th>Goal<\/th><\/tr><\/thead>
Day 0<\/td>Welcome with a single first step<\/td>Get off to a good start<\/td><\/tr>
Day 1<\/td>Quick guide or short video<\/td>Sort out the setup<\/td><\/tr>
Day 3<\/td>Reminder if they have not completed the first step<\/td>Win back those who get stuck<\/td><\/tr>
Day 5-7<\/td>Case study or advanced tip<\/td>Show what they can achieve<\/td><\/tr>
Day 10-14<\/td>Offer of personal help<\/td>Prevent drop-off<\/td><\/tr>
Day 30<\/td>Summary of what they have achieved and next step<\/td>Move on to adoption<\/td><\/tr><\/tbody><\/table><\/figure>\n\n

What works best is a sequence driven by behavior. If the customer has already completed a step, do not remind them of it: move on to the next one.<\/p>\n\n

To set it up, you need an autoresponder<\/a> or a mailing automation<\/a> system that sends each email based on each contact’s signup date and actions.<\/p>\n\n

Examples by type of business<\/h2>\n\n

Software or app (SaaS<\/a>).<\/strong> The goal is for the customer to complete the setup and use the main feature. Each email shows a single step, with a button that takes them straight to that screen.<\/p>\n\n

Online store.<\/strong> After the first purchase, onboarding explains shipping, how to use the product and which products go well with it. The goal is the second purchase.<\/p>\n\n

Professional services.<\/strong> A consultancy, a school or a gym explains what will happen in the first few weeks, what they need from the customer and who to contact. The goal is for the customer to feel that the service has already begun.<\/p>\n\n

Metrics to measure customer onboarding<\/h2>\n\n

Activation rate.<\/strong> Customers who reach their first result out of total signups.<\/p>\n\n

Time to first value.<\/strong> Days between signup and activation. The shorter, the better.<\/p>\n\n

Step completion.<\/strong> Which part of the sequence makes customers stop.<\/p>\n\n

Early cancellations.<\/strong> Customers who leave within the first 30 or 90 days. This is the part of the churn rate<\/a> that depends most on onboarding.<\/p>\n\n

Clicks per email.<\/strong> Which messages really help and which ones can be removed.<\/p>\n\n

\"Customer<\/figure>\n\n

Common mistakes<\/h2>\n\n

Explaining everything in the first email.<\/strong> A new customer cannot learn ten features at once. One step per email is enough.<\/p>\n\n

Sending the same sequence to everyone.<\/strong> Someone who has already started does not need the same reminders as someone who has never logged in.<\/p>\n\n

Selling too soon.<\/strong> Before you offer a higher plan, the customer needs to have seen the value of the one they already have.<\/p>\n\n

Not leaving a human way out.<\/strong> A link to support or a direct reply to the email prevents many cancellations.<\/p>\n\n

Not reviewing the sequence.<\/strong> Every few months, check where customers stop and adjust that email.<\/p>\n\n
