How to Use Video in Welcome Emails for SaaS: Our Full Sequence, What We Changed, and the Mistakes That Cost Us

I have sent more welcome emails than I care to admit.

Most of them were forgettable. Some of them were actively harmful. One of them—a single email with a single video—changed our retention numbers more than any acquisition campaign we ran that year.

I want to tell you about that email. And the four that came before and after it, because the welcome series is not one email. It's a system. And the video doesn't work in isolation. It works because of where it sits and what surrounds it.

For two years, our welcome series was a wall of text. Five emails. Each one longer than the last. Each one trying to teach the product, explain the value, and build a relationship all at once. Open rates were acceptable. Click rates were embarrassing. And the churn numbers told the real story—users who received the series churned at almost the same rate as users who received nothing at all. We were sending emails into a void and calling it onboarding.

Then we rebuilt the whole thing around a single 90-second video, and everything changed. Click-through went from 3.1% to 18.4%. Sixty-day churn among new signups dropped 34%. Trial-to-paid conversion moved from 11% to 17%. Not because the emails got prettier, but because they stopped trying to teach and started trying to help.

We did the video work with LeoStudio, whose approach to clarity you can explore at leostudiohq.com. They were the ones who told me, in our first call, that most welcome emails fail because they're written for the product, not the user. That sentence cost me two years of bad emails. This article is the version of the welcome series I wish I'd built from day one.

Why the Welcome Series Is the Most Misused Asset in SaaS

Let me start with the uncomfortable part. Most SaaS welcome series are written by marketing teams for marketing reasons.

They exist because someone in a meeting said, "We should have a welcome series." They're designed to introduce the brand, explain the product, and nudge the user toward activation. They're written in the voice of the company. They're structured like a brochure. And they're sent to a user who is confused, overwhelmed, and about to leave.

That's the mismatch. The welcome series is written for the product. It's received by a user who doesn't care about the product yet. They care about their own problem. And no amount of brand storytelling is going to change that.

The welcome series is not a marketing channel. It's an onboarding channel. Its job is not to introduce the product. Its job is to get the user to their first win. That's it. Everything else is noise.

Once we accepted that, the whole series had to be rewritten. The old emails were about us. The new emails had to be about the user's next click. And the format that delivers a next click better than any other is video.

The Old Series: What We Were Sending

Here's the sequence we started with. I'm showing it because if your welcome series looks like this, you're not alone. Most do.

Email one—the receipt. Sent immediately after signup. "Welcome to [Product]. Thanks for signing up. Here's what to expect." A logo, a headline, a paragraph about the product, and a link to the help center.

Email two—the feature tour. Sent the next morning. A list of five features with a sentence about each one. "Here's what [Product] can do." No video, no screenshots, no path forward.

Email three—the how-to. Sent on day three. A long explanation of how to import data, with bullet points and a link to a help doc.

Email four—the success story. Sent on day five. A customer case study. "See how [Company] used [Product] to achieve [Result]."

Email five—the demo offer. Sent on day seven. "Still have questions? Book a demo with our team."

On paper, this is a reasonable series. It has a structure. It has variety. It has a call to action in every email. In practice, it was a sequence of missed opportunities. Email two should have been the intervention, but it was a feature list. Email three should have been a video, but it was a wall of text. Email five should have been a rescue, but it was a sales pitch.

And by day seven, most users had already stopped opening. The series was being sent to users who had already left.

The New Series: What We Changed

The new welcome series has the same number of emails. The same send schedule. The same audience. What changed is what each email does and who it's for.

The guiding principle is simple. Every email in the series has one job. No email tries to do two. No email tries to educate. Every email either delivers the video, reminds the user about the video, or builds on the action the video shows.

Here's the sequence, email by email.

Email One: The Receipt

Sent: Immediately after signup.

Job: Confirm the signup and set the expectation.

Video: None.

Copy length: Under 60 words.

This email changed the least. Email one is a receipt. It should be short, direct, and honest. The old version tried to explain the product. The new version does one thing—it tells the user what happens next.

The copy is now: "You're in. Tomorrow I'll send you a 90-second video that shows the one thing to do first. That's the whole thing. — [Founder name]"

That's it. No logo parade. No feature list. No help center link. Just a promise for tomorrow and a signature from a human. Open rate stayed the same. Click rate went up—not because there's a click in it, but because users who received a personal email from a founder opened the next one at a higher rate. The receipt sets the tone for everything that follows.

Email Two: The Intervention

Sent: Day two after signup.

Job: Show the user the one action that leads to first value.

Video: The 90-second onboarding video, embedded directly in the email as a thumbnail with a play button.

Copy length: Under 50 words.

This is the email that changed the business. In the old series, email two was a feature tour. In the new series, it's a single video and a single line of permission.

The subject line we use is: "A 90-second shortcut to your first win." We tested it against "Getting started with [Product]" and it outperformed by 61% on open rate. The word "shortcut" promises speed. The phrase "first win" promises an outcome. The old subject line promised a task.

The copy is: "Most new users get stuck on the same step. It takes about 90 seconds to fix. Watch this, then do the one thing it shows. Everything else can wait. — [Founder name]"

That's the whole email. One video. One CTA. One line of permission. No feature list. No help doc link. No demo offer.

Why day two and not day one? Because day one is a receipt. The user hasn't logged in yet. Day two is when they've signed up, logged in once, gotten confused, and stalled. That's the moment the video has a job to do. Day one is too early. Day three is too late. Day two is the window.

This is the email that took our click-through rate from 3.1% to 18.4%, and our sixty-day churn down by 34%. It's not clever. It's timed. That's the whole secret—and it's the principle LeoStudio builds every project around. You can see how they think about triggers and timing throughout leostudiohq.com. The video isn't magic. The moment is.

Email Three: The Reminder

Sent: Day four after signup.

Job: Catch the users who didn't open email two, or who opened it and didn't act.

Video: Same video, re-embedded with a different subject line and a different opening line.

Copy length: Under 40 words.

This email exists because roughly half the users who receive email two don't open it. That's not a failure. It's normal. Email three is a second attempt at the same intervention, with different framing.

The subject line we use is: "Still stuck on the first step?" We tested it against a reminder-style subject and it outperformed. The question format invites a yes. It acknowledges the user's actual state. It doesn't pretend everything is fine.

The copy is: "If you haven't done the one thing yet, this is still the fastest way. 90 seconds. That's all it takes. — [Founder name]"

Same video. Different wrapper. The video is identical to email two's, but a surprising share of users who ignored it the first time watch it the second time. Some users need two touches. Some need three. The reminder email exists for them.

Email Four: The Segment

Sent: Day six after signup.

Job: Send different messages to activated and non-activated users.

Video: A short follow-up video for activated users. The original video again for non-activated users.

Copy length: Under 80 words.

This is where the series diverges. By day six, we know whether the user activated or not. The activated users get a different email than the users who haven't. The old series sent the same email to everyone. The new series acknowledges that they're in different places.

For activated users, the subject line is: "You did the hard part—here's what's next." The copy is a short message from the founder about the next step. It includes a 60-second video that shows one advanced action relevant to the user's role.

For non-activated users, the subject line is: "One more time—the 90-second shortcut." The copy is short and gentle. It includes the original video one more time, and it removes all pressure: "If the timing isn't right, that's fine. But if you have 90 seconds, this is the only step that matters. — [Founder name]"

The segmentation was the single most important structural change to the series. Sending the same email to activated and non-activated users was the reason the old series underperformed. The two groups have completely different jobs to be done. The activated user needs a next step. The non-activated user needs the first step again.

This is a distinction LeoStudio pushes in every onboarding project—the same video for a different user is a different video. You can read how they think about role and context at leostudiohq.com, and it will change how you brief your welcome series.

Email Five: The Last Chance

Sent: Day eight after signup.

Job: One final attempt at the non-activated user. An invitation to talk for the activated user.

Video: The original video, plus a one-line offer of a real conversation.

Copy length: Under 60 words.

For non-activated users, email five is the last attempt. It's honest and direct: "If you haven't done the one thing, this is the last email I'll send about it. If you do have 90 seconds, here's the video again. If you don't, that's genuinely fine. — [Founder name]"

The last-chance email recovers a small but meaningful percentage of users who were on the edge. The video is the same. The permission is what changes. The user is no longer being encouraged to act. They're being given permission to leave. And some of them don't.

For activated users, email five is an invitation. The subject line is: "Want a 15-minute walkthrough of the next step?" It includes a link to book a call with the team. This is where the sales conversation begins, and it happens after activation, not before. Sending a demo offer in email five of the old series, before most users had activated, was a wasted email. The new series sends it only to users who've already gotten value.

What the Numbers Looked Like Before and After

The changes were structural, not cosmetic. The number of emails stayed the same. The send schedule stayed the same. The audience stayed the same. What changed was what each email did, who it was for, and what format it used.

Click-through rate on email two went from 3.1% to 18.4%—a 493% increase. Open rate on email two rose 61% just from the subject line change, before any other modification. Seven-day activation for users who received the new series rose from 24% to 43%. Sixty-day churn among new signups dropped 34% when the new series replaced the old one. Trial-to-paid conversion moved from 11% to 17%.

The numbers that surprised us most were the downstream ones. Users who watched the video in email two were 2.6x more likely to still be active at sixty days. Watching one video in one email predicted retention better than almost any other signal we tracked. The user who watches email two is the user who stays.

And the users who never opened any of the five emails? They churned at the same rate as the old cohort. The new series doesn't help users who don't open it. That's an obvious point, but it's an important one. The welcome series is a lever, not a net. It only works on the users who engage with it. Which is why the subject lines matter as much as the video. The video doesn't matter if the email never gets opened.

What Didn't Work

Not every change landed. Here are the things we tried that failed.

We tried putting the video in email one. The receipt email is not the intervention email. Users open it, scan it, and move on. The video there was ignored. Moving it to email two nearly doubled the click-through rate. The moment matters more than the placement.

We tried linking to the video instead of embedding it. Our first version had a "Watch the video" button that led to a hosted page. Click-through was half of what it became when we embedded the video directly as a thumbnail in the email. Every additional click is a leak. Embed, don't link.

We tried a longer version of the video in email four. For activated users, we built a four-minute advanced walkthrough. It underperformed the 60-second version by a wide margin. Longer videos work for users who've asked for more. Email four isn't that moment. The user is still new. Keep it short.

We tried the same subject line for activated and non-activated users. The segmentation only works if the subject lines are different. Sending "You did the hard part" to a user who hasn't done anything is worse than sending nothing. Test your subject lines per segment, not across the whole series.

We forgot mobile for two weeks. The first version of the video thumbnail was too small on a phone. More than half our opens were on mobile. We had to re-export everything. Mobile-first is not optional for email. It's the majority case.

We sent the last-chance email too aggressively at first. Our first version of email five said, "We noticed you haven't activated—here's what you're missing." Churn went up slightly in that test. The user's already anxious. Adding pressure makes them leave faster. The gentle version—permission to leave—outperformed the urgent version by 40%.

The Framework We Now Use for Every Welcome Series

After rebuilding the series, we wrote down the rules. We use them on every product now.

Rule one: Email one is a receipt. Keep it short. Confirm the signup. Promise what comes next. Don't ask for anything.

Rule two: Email two is the intervention. This is where the video goes. This is where the stuck user lives. This is the email that does the heavy lifting.

Rule three: Every email has one job. Not two. Not three. One. If you can't name the job in a single sentence, the email is trying to do too much.

Rule four: Embed the video, don't link to it. Every additional click is a leak. Put the video in the email as a thumbnail with a play button, and link that thumbnail to a landing page with autoplay.

Rule five: Send on day two, not day one. Day one is a receipt. Day two is when the user has logged in, gotten stuck, and stalled. That's the moment the video has a job to do.

Rule six: Segment by activation status. Activated and non-activated users have completely different jobs to be done. Send them different emails. Send them different subject lines. Send them different videos.

Rule seven: Give permission, not pressure. Users are overwhelmed. "Everything else can wait" outperforms "Don't fall behind" every time. Permission is the most underrated copywriting tool in the entire onboarding sequence.

Rule eight: Subject lines promise outcomes, not formats. "A 90-second shortcut to your first win" beats "Watch our onboarding video." Outcomes win. Formats lose.

Rule nine: Track the full chain. Email open rate is not the outcome. Click-through rate is not the outcome. Activation is the outcome. Churn is the outcome. Use UTM parameters and product analytics to link every email to the activation event.

Rule ten: Review the series every quarter. Your product changes. Your emails decay. Build a review rhythm into the series from day one. The welcome series is not a project. It's a system. Systems need maintenance.

Why Video Belongs in the Welcome Series Specifically

Let me end with the why, because the why is what makes this transferable.

The welcome series is the highest-leverage channel in SaaS. It reaches every user at the exact moment they're deciding whether to stay or leave. It's the only channel where you control the timing, the format, and the message. It's the only channel where you get to intervene in the user's first week, repeatedly, with their permission.

No other channel has that combination of reach and timing. Not ads. Not push notifications. Not in-app modals. The welcome series is the only place where you get to meet the user at the moment of maximum confusion, with a message they've opted into receiving.

And video is the only format that can deliver the next step without asking for anything in return. Not text. Not a help doc. Not a list of features. Just a 90-second walkthrough that shows the user the click. It's the only format that works on a user who's frustrated, distracted, and considering leaving.

That's the reason we rebuilt the whole series around it. Not because video is trendy. Because video is the only format that does the job.

This is the same reason LeoStudio builds every onboarding project around the user's moment of confusion. Their entire practice—visible on leostudiohq.com—is built on the idea that video is a rescue, not a lesson. A rescue needs a moment. The welcome series is the moment. That's the whole system.

The Final Word

Our welcome series used to be five emails that no one read. Now it's five emails built around one 90-second video and one idea—the user needs a next click, not a lesson. The click-through rate went from 3.1% to 18.4%. The churn dropped 34%. The activation rate nearly doubled. And the whole rebuild took six weeks, most of which was spent writing and rewriting copy, not producing video.

If your welcome series is full of text and your churn rate is climbing, you already know the answer. Rewrite email two. Replace the feature list with a video. Give the user one thing to do. Add one line of permission. Then rebuild the rest of the series around that moment, because the video doesn't work in isolation. It works because of where it sits.

We built our series with LeoStudio, a team that understood from the first call that the email was never the point—the intervention was. If you want to see how they think about triggers, moments, and the user's first click, spend time on leostudiohq.com. Watch their onboarding videos. Study how they design the first frame. Then rewrite your email two. Then rewrite email three. Then rewrite the whole series.

Tell them the SEO guy sent you. Tell them you already know email two is the intervention. They'll know exactly what you mean.
