A welcome series that turns signups into customers

The short answer

A welcome email series is a short set of automated emails sent to every new subscriber. For most small businesses, three to five emails over 10 to 14 days works well: the first sent immediately to deliver what you promised, then one every two to four days that introduces your business, shows proof that you are worth trusting, answers the main objection and makes a clear first offer. Each email should have one job and one main link.

It is usually the first automation to set up, because new subscribers pay the most attention right after they join. Below is a ready-to-adapt plan, with variations for online stores, service businesses and B2B firms.

A five-email welcome series template

1. Email 1, immediately: deliver and set expectations. Send the discount code, guide or resource they signed up for in the first lines. Then say what you will send and how often. Ask them to add your address to their contacts or reply with a question. Replies are a good engagement signal for inbox providers.
2. Email 2, day 2 or 3: who you are. A short story of why the business exists, who runs it and who you help. A photo of the team or the place works better than a stock image.
3. Email 3, day 4 to 6: proof. Two or three short reviews or a before-and-after example, plus one number you can stand behind, such as years in business.
4. Email 4, day 7 to 9: answer the main objection. Price, fit, timing or risk. Explain how it works, what it costs to get started or what happens if it is not right for them.
5. Email 5, day 10 to 14: the clear ask. Remind them of the offer and any deadline, or invite them to book. Then move them to your regular newsletter.

Timing rules that work

• Send email 1 instantly. A delay of hours loses people who signed up for something specific.
• Space later emails two to four days apart. Closer feels pushy; further apart and they forget.
• Pause regular campaigns for people in the series, so a new subscriber does not get a welcome email and a promotion on the same day. Most platforms let you exclude contacts currently in a flow.
• Exit people who convert. If someone buys or books during the series, stop the sales emails and send a thank-you or onboarding message instead.
• Send at a sensible local time for later emails, if your platform supports it.

Writing and design tips

• Subject lines that say what is inside. “Your 15% code is inside” beats something clever. It also keeps you on the right side of CAN-SPAM, which requires subject lines that reflect the content.
• Short emails. 75 to 200 words is plenty for most welcome emails. Link to the website for detail.
• One button, placed early. Repeat it at the end if the email is long.
• Mobile first. Single column, large text, buttons big enough to tap.
• Plain-text feel for service and B2B. An email that looks like it came from a person often gets more replies than a heavily designed one.
• Required footer. Your postal address and an unsubscribe link, per CAN-SPAM, even in automated emails that promote anything.

Setting it up in your platform

All the main platforms support welcome series, but the details differ:

• Mailchimp: marketing automation flows handle multi-step series. As of 2026, Mailchimp’s help center says Essentials plans are limited to flows of up to 4 steps, while Standard and higher allow up to 200 steps and conditional splits. A five-email series with waits needs Standard.
• Klaviyo: a list-triggered flow starts when someone joins your signup list. You can branch the series based on whether they have ordered.
• Shopify Email (now Shopify Messaging): includes automation templates. Shopify’s help center says these automated emails count toward the 10,000 free emails a month, except abandoned checkout emails.
• HubSpot: workflows can enroll contacts by form submission and update lifecycle stage as they engage.

If you use double opt-in, the welcome series should start after confirmation, not at the first form submit.

How to measure a welcome series

• Click rate per email. Find the email where interest drops and rewrite it.
• Conversion rate for the whole series. The share of new subscribers who buy, book or reply within 30 days.
• Unsubscribes per email. A spike on one email means its content or timing is off.
• Revenue or leads attributed to the flow compared with your regular campaigns.

Review it every quarter. Update offers, swap in fresh reviews and test one change at a time, such as the subject line of email 1 or the offer in email 5.
