SaaS Launch Checklist: Everything You Need Before You Go Live
Most SaaS products don't fail at launch. They fail in the two weeks before it.
The product is mostly built. The founder is exhausted from months of development. They pick a date, post a tweet, and go live. The checkout doesn't work. The ICP is still vague. There's no outreach list. The analytics aren't hooked up. Three people visit the site. One of them is the founder's mom.
That's not a bad launch. That's a launch with no preparation.

Why Checklists Matter at Launch
Launch is the highest-pressure week of building a product. Your brain is in execution mode, which means it defaults to what's familiar and skips what's uncomfortable. Defining your ICP precisely is uncomfortable. Testing your own checkout with a real credit card is uncomfortable. Writing a cold outreach sequence to 50 people is uncomfortable.
A checklist doesn't care how you feel. It just tells you what's undone. That's why it works.
The Pre-Launch Checklist (30 Days Out)
Thirty days before launch, none of these should be open questions. Work through them in order — each one depends on the previous.
-
ICP defined. You have one specific person, not a category. Not "small businesses" or "freelancers." One person: "Maya, 34, runs a 3-person marketing agency, has 8–12 clients at once, and loses 3–5 hours a week chasing unpaid invoices." If you can't describe your customer that specifically, stop here and do this first. Everything downstream — your landing page, your pricing, your outreach — depends on it.
-
Demand validated. At least 5 people who fit your ICP have said "I'd pay for this" — not "interesting," not "maybe," but an explicit "yes, that's a real problem and I'd pay to fix it." If you haven't done this yet, validate your idea before you build anything else.
-
Landing page live. Hero section, problem statement, solution description, and a clear CTA — that's the minimum. It needs an email capture form that actually works. Your minimum viable landing page doesn't need to be beautiful; it needs to communicate who this is for and what they get. Test it on mobile.
-
Pricing set. One clear tier for first customers. Don't build a three-tier pricing table before you've charged a single person. Pick a number that feels slightly too high to you — it's probably right. If you've validated with 5 people, ask them what they'd pay. Anchor to that.
-
Checkout tested. Run a real payment with your own credit card. Confirm the money hits your account. Confirm the email confirmation goes out. Confirm the confirmation email says the right thing, goes to the right address, and has a working next-step link. You'd be surprised how many launches have checkout broken on day one — the founder only ever tested with a test card.
-
Outreach list built. 50 warm contacts who fit your ICP — by name, with a note about why they're a fit. LinkedIn, Reddit threads where your buyer vents about the problem, your network, people you've already talked to during validation. This is the list you'll contact in week one. If you can't build 50 names in the relevant problem space, your ICP may still be too broad.
-
Email sequence drafted. Three emails minimum: an introduction (what you built and why), a follow-up for non-responders, and a breakup email ("I won't follow up after this — just wanted to make sure you saw it"). Keep each under 150 words. The intro email should sound like it was written to one person, not blasted to a list.
-
Analytics live. GA4 or equivalent on every page — not just the homepage. You need to know where people land, where they bounce, and whether anyone hits the checkout page. Set up a conversion event on your CTA click or email form submission. If you don't have this before launch, you'll have traffic you can't interpret.
The Launch-Week Checklist
This is the week your product goes public. Every item here should happen in the first 5 days.
-
Announcement email to your list (day 1). Personal tone, first person, short. "I've been working on something and I want you to be among the first to try it." Not a marketing blast — a note from you to a person. Write it like you'd write to a friend who has the problem.
-
LinkedIn post. Your story, not a product ad. What problem were you personally dealing with? Why did you build this? What did you learn? The post should make someone feel something before they know what the product does. Product features are a footnote; your story is the hook.
-
Reddit post in relevant communities. r/SideProject, r/entrepreneur, and at minimum one niche subreddit where your ICP actually hangs out. Read the community rules before posting. Most subreddits respond well to "I built this because I kept running into X problem — feedback welcome" and very poorly to "check out my new product." Lead with the problem and the journey.
-
Indie Hackers post. Use the product launch section. Write a real retrospective — what you validated, what you built, how long it took, what you learned. IH readers specifically want the journey, not the marketing pitch. This also builds a permanent SEO-indexed record of your launch.
-
Product Hunt — submit if prep is done. Don't rush this. If you haven't done the 30-day pre-launch prep — maker profile complete, email list warmed, notification list ready — wait. A bad PH launch is worse than no PH launch because it buries your product in the archive. If the prep is done, launch on Product Hunt at 12:01am PST with your first comment ready to post within 60 seconds.
-
Show HN if it's a dev tool. Post "Show HN: [what it does in plain English]" on a weekday between 8–11am ET. Keep the description factual and specific — HN readers are allergic to marketing language. Link directly to the thing, not to a landing page.
-
DM 10 warm contacts personally. Not a template blast. Ten individual messages, each with one sentence that's specific to that person. "Hey — you mentioned the X problem in that thread a few weeks ago. I built something for exactly that. Mind taking a look?" These 10 conversations are worth more than 1,000 cold impressions.
-
Monitor replies and respond within 60 minutes. Every comment, every DM, every email reply. Speed signals that a real person is behind the product. This is especially important in the first 24 hours on Product Hunt and Reddit, where early engagement velocity affects ranking.
The Post-Launch Checklist (First 2 Weeks)
Most founders stop after launch week. This is the part that actually determines whether you have a product or a one-day spike.
-
Talk to every user who signs up. Within 24 hours. Calendly link in the welcome email, or a direct DM if you know who they are. Not a survey — a real conversation. The questions that matter: "What made you sign up? What were you hoping to solve? What were you doing before this?" One conversation worth more than 100 survey responses.
-
Track signups, activations, and churns — not just traffic. Traffic is a vanity metric at this stage. What matters: how many people signed up, how many of them actually used the product (activated), and how many didn't come back (early churn). Find your first 10 customers by obsessing over activation — people who sign up and never use the product are almost never going to convert to paid.
-
Run the Sean Ellis test at week 2. Once you have 5+ users who've actually used the product, ask them one question: "How disappointed would you be if this product went away?" The benchmark is 40% saying "very disappointed." Under that, you don't have product-market fit yet and you need to understand what's missing before scaling anything. This is the most signal-dense question you can ask at this stage.
-
Iterate the landing page based on what users actually say. Not based on what you think. The phrases users use to describe their problem and the outcome they want are almost always better landing page copy than what you wrote. If three users describe their problem the same way, that's your new hero headline. Update the page by end of week 2.
-
Make a clear decision: continue, pivot, or kill. Based on data, not feelings. Signals that say continue: paying users, activation rate above 30%, repeat usage, "very disappointed" score at 40%+. Signals that say pivot: signups but no activation, activation but no retention, "somewhat disappointed" being the top answer. Signals that say kill: no signups, no engagement, nobody can describe what problem it solves.
The 3 Things Founders Skip That Kill Launches
These aren't edge cases. These are the failure modes that show up in nearly every launch that doesn't work.
Skipping validation before building. You launch to silence because you built for a problem that doesn't exist acutely enough for anyone to pay for. The fix is demand validation before the product is built — not after. Five people saying "I'd pay for this" isn't a hard bar; it just takes a few days of real conversations.
Skipping a real checkout test. Not a test-mode transaction. A real card, real charge, real email confirmation. Payment integrations have edge cases that test mode doesn't surface — failed webhooks, confirmation emails that go to spam, success pages that break on mobile. If this fails on launch day, every motivated customer you've been waiting months for bounces out of checkout and doesn't come back.
Skipping post-launch user conversations. The common pattern: build, launch, wait for data. The data arrives as an aggregate (signups, page views, conversion rate) and tells you nothing about what to change. The founders who iterate fastest are the ones talking to their users within 24 hours of signup. Not asking for feature requests — asking about their problem and their experience. You can't improve what you don't understand.
A Launch Isn't a Moment — It's a 6-Week Process
The most important thing to understand about launching is that it's not a day. It's 30 days of preparation, a week of execution, and two weeks of follow-through.
Most of the work happens before you go live. The checklist above is a map of that work — not a substitute for it. You still have to do the hard things: define who you're actually building for, talk to real people, test the payment flow, draft the emails, and then have the conversations after launch that tell you whether it's working.
The checklist is just a forcing function. The real work is talking to people.
