How to Find the Right Newsletter for Your SaaS Product (Step-by-Step)

Most SaaS teams that try newsletter advertising make the same first mistake: they pick newsletters they've heard of rather than newsletters their buyers actually read.

The result is a placement in a well-known publication with a broad audience, weak click-through, and a conclusion that newsletter ads don't work. The channel gets written off before it's been properly tested.

Finding the right newsletter for your SaaS product is a research problem, not a creative one. Get the targeting right first. Here's how to do it step by step.

Step 1: Write a One-Sentence ICP Statement

Before opening any discovery tool, write down who you're trying to reach in one sentence. Be specific enough that a stranger could identify your buyer from the description.

Too vague: "B2B marketers at tech companies"

Specific enough: "Heads of demand generation at Series B SaaS companies with 50–200 employees who are responsible for pipeline from paid channels"

This sentence becomes your filter for every newsletter you evaluate. If a publication's audience doesn't match this description, it doesn't make your shortlist — regardless of how large or well-known it is.

Step 2: Map the Categories Your ICP Reads

Think about your buyer's reading habits, not their job title. What newsletters would someone in that role subscribe to in order to stay sharp at their job?

A demand generation manager might read:

• Marketing strategy and B2B growth newsletters
• SaaS metrics and benchmarking digests
• Paid acquisition and performance marketing newsletters
• Revenue operations newsletters

Each of these is a search category. Write down 3–5 before moving to discovery.

Step 3: Search a Newsletter Discovery Database by Category

This is where most teams waste the most time if they don't have the right tool. Manually searching Google for each category, visiting individual newsletter websites, and tracking down sponsorship contacts can take days.

A newsletter discovery platform like Lettrbase lets you search by category and surface a library of leads instantly — technology, business, and other verticals return 50–80+ leads per search. Export those leads and you have a research pool to work from in minutes, not days.

Step 4: Qualify Each Newsletter Against Four Criteria

From your discovery list, request media kits from 10–15 publications and evaluate each against:

1. Audience description match Does the operator describe their readers in terms that match your ICP statement? The more specific, the better. "Our readers are B2B SaaS marketers at growth-stage companies" is a green flag. "Our readers are business professionals" is a red flag.

2. Open rate A higher open rate indicates an engaged, trusting audience. Ask for this number in the media kit. Compare it relative to list size — a smaller list with a high open rate often outperforms a large list with low engagement.

3. Sponsor slots per issue Fewer is better. One or two sponsors per issue means your ad gets real attention. Four or more means you're competing with other brands inside the same email.

4. Editorial quality Read 3–5 back issues before committing. Is the content genuinely useful? Does the operator have a distinct voice? Newsletters with strong editorial quality have readers who trust the curator's recommendations — including yours.

Step 5: Test With a Small Budget Before Scaling

Once you've shortlisted 3–5 newsletters, run single-issue placements with:

• A UTM-tagged link for each newsletter so you can measure traffic by source
• A dedicated landing page or offer specific to newsletter traffic
• Consistent ad copy across all placements so you're testing the audience, not the creative

Give each newsletter 2–3 placements before drawing conclusions. One issue is not enough data.

Step 6: Double Down on What Works

After 60–90 days, you'll have real data on which newsletters are sending traffic that converts. Reallocate budget toward those publications. Negotiate multi-issue packages for lower rates. Build a direct relationship with the operator — the best newsletter sponsorships are long-term partnerships, not one-off transactions.

The Most Common Mistake to Avoid

Skipping Step 1. Teams that start with newsletter discovery before defining their ICP end up with a long list of plausible-looking publications and no clear way to prioritise them. The ICP statement is what makes the rest of the process fast.

Lettrbase gives SaaS teams a searchable newsletter lead database organised by category. Define your ICP, identify your categories, and surface a qualified research pool in minutes — so you can spend your time on evaluation and outreach, not hunting for publications.
