Most people who try to setup email newsletters focus on picking a template. They write one good email. Then they wonder why opens and clicks fade within weeks. The real work is a permission-based list, a repeatable send and a way to read the numbers.
Key Takeaways
- Across industries, the average newsletter open rate is 35.63%, and the average click rate is 2.62% (Mailchimp). Compare your own newsletter against these, not against a single “good” number.
- Keep your spam complaint rate below 0.3% in Gmail Postmaster Tools. Aim for under 0.10%. Above that, Gmail may start routing your newsletter to spam (Google).
- US law requires a working unsubscribe link, honoured within 10 business days. Fines reach up to $53,088 per violating email (FTC CAN-SPAM Act).
- Senders of more than 5,000 emails a day must support one-click unsubscribe. They must also authenticate with SPF, DKIM and DMARC (Google sender guidelines). Smaller senders should still set up SPF and DKIM from day one.
- Morning Brew’s newsletter grew from 20 family members to about 10,000 subscribers through a campus referral programme, before it became profitable. It has since grown to roughly 4.5 million (Morning Brew). List quality mattered more than one viral email.

Why Most Attempts to Setup Email Newsletters Stall
A newsletter is easy to start. It is just as easy to abandon. The first few issues get written with care. Open rates look fine, because the list is small and warm. Then growth slows. New subscribers trickle in. Old ones stop opening. Nobody checks why.
The cause is rarely the writing. It is usually one of three setup gaps. The list was built without real permission. The send has no fixed cadence. Or nobody reads the metrics that explain reader behaviour.
This guide treats the job of setting up an email newsletter as four tasks. Build the list correctly. Design a repeatable issue. Protect deliverability. Measure what readers do. Get these four right once, early, and most of the maintenance work disappears.
Worldwide, around 6.04 billion people are online, according to the DataReportal Global Overview Report. For most newsletters, the real ceiling on growth is permission and list quality, not population. Treat every figure below as a baseline, not a guarantee. Benchmarks vary by list size, industry and how a list was built. Always compare a newsletter against its own past performance first.
How to Setup Email Newsletters: The Technical Foundation
Behind every newsletter send is a short chain. A subscriber opts in. An email service provider (ESP) stores their address and preferences. A campaign is composed and scheduled.
Then the receiving mail server (Gmail, Outlook, Yahoo and others) decides whether to deliver it to the inbox, a promotions tab, or spam. Everything you do to setup email newsletters correctly happens somewhere in that chain, usually before the first real issue goes out.
Three technical pieces decide that last step. All three happen once, at setup, not per email. (For a deeper walkthrough of what each inbox provider checks, see our guide to email deliverability.)
- Double opt-in. A new subscriber confirms their address by clicking a link in a confirmation email. This keeps fake and mistyped addresses off the list.
- Authentication (SPF, DKIM, DMARC). These are DNS records. They prove an email claiming to be from your domain really did come from your sending system. Google’s sender guidelines require SPF and DKIM for every sender, and all three for anyone sending more than 5,000 emails a day.
- A dedicated sending domain and a steady pattern. Mailbox providers score a sending domain on complaint rate, bounce rate and engagement over time. A sudden volume spike or a long gap hurts deliverability more than one bad email does.
Get these three right before writing a single issue. A well-designed newsletter that lands in spam, or gets flagged for weak permission, never gets read. It does not matter how good the writing is.
What Differs by Newsletter Type
“Email newsletter” covers several different jobs. The setup that works for one can hurt another. If you plan to setup email newsletters for more than one purpose, treat each as its own project. Do not reuse one template for all three.
Content Newsletters: Built For Trust
A content newsletter (a weekly roundup, a digest, a personal note) is useful on its own, with no immediate ask. Its job is a reliably high open rate over months, so subscribers treat it as a habit, not one more promotional email to skim and delete.
Promotional Newsletters: Built For Conversion
A promotional newsletter (offers, launches, cart reminders) exists to drive a click, then a specific action. Its job is a strong click-to-open rate on a narrow set of sends. It is judged by a different metric from day one, not by overall open rate.
Transactional-Style Newsletters: Built For Timing
A transactional-style newsletter (a welcome series, a weekly account summary, a renewal reminder) arrives at a predictable moment tied to something the subscriber already did. Its job is timing accuracy, and a late or mistimed send hurts trust more than a weak subject line does.
This is the type most people mean when they ask how to setup email newsletters for an existing product, since it rides on events the business already tracks rather than on a content calendar.
How to Set Up Each Newsletter Type
Each type above needs a different first move. Trying to setup email newsletters with one generic process for every job produces an email that half-serves every job, and fully serves none.
Content Newsletters: Lead With a Fixed Cadence
Pick one send day and time. Keep it for at least ten issues before changing anything. Readers build a habit around predictability. A fixed cadence also gives you a clean baseline, since you can only tell if a subject-line change worked when the send time stayed the same.
Promotional Newsletters: Lead With Segmentation
Split the list before writing the email, not after. Separate buyers from browsers, and active subscribers from those inactive for 90 days. A promotional send to an unsegmented list usually produces a mediocre click-to-open rate overall. The same offer, segmented by recent behaviour, typically performs better for the right group, and annoys fewer of everyone else.
Transactional-Style Newsletters: Lead With Trigger Logic
Map the exact event that should fire each send first: signup, purchase, inactivity, or a renewal date. Most ESPs call this an automation or a journey. Get the trigger and delay right before you write the email, because a good email sent at the wrong moment reads as careless, no matter how carefully it was worded.
If your newsletter is one tool among several, our guide to building a martech stack your team will actually use covers how to pick and connect an ESP without over-buying tools. Choosing the right ESP is also part of how you setup email newsletters that scale past a few hundred subscribers without constant manual work.
How to Setup Email Newsletters With a List Built on Permission
Every reliable newsletter starts the same way: permission first, volume second. A bought or scraped list fails even if the first send looks fine. One send with a high complaint rate can damage a sending domain’s reputation for every future email, including to people who opted in properly.
This is the step most guides to setup email newsletters skip, because it is slower than picking a template. It still decides whether every later step works, and skipping it to save a week of list-building usually costs far more than a week later on.
- Add a visible, specific signup form. State exactly what subscribers will get (“one digest every Tuesday”), not a vague “join our newsletter” line.
- Use double opt-in for public signup forms. It adds a little friction. In exchange, it removes mistyped and fake addresses before they ever receive a send.
- Send a welcome email immediately. Almost every subscriber opens this one. Use it to confirm what they signed up for, and set the cadence they should expect.
- Give subscribers a one-click way to update preferences or leave. A subscriber who can adjust frequency usually stays on the list. One who cannot easily leave is more likely to mark the email as spam instead, which hurts deliverability far more than an unsubscribe does. This is also an easy early win inside our broader guide to customer retention management, since a subscriber who leaves cleanly can often be won back later.
Common Mistakes When People Setup Email Newsletters
Most newsletter problems trace back to one of a small set of setup mistakes. They repeat across almost every industry. Checking for these before your next send usually finds the real issue faster than rewriting the copy.
Mistake: No Consistent Sender Identity
Switching the “From” name or sending domain between issues resets some of the trust signals mailbox providers track. It also confuses subscribers scanning a crowded inbox. Pick one sender name and one domain when you first setup email newsletters, and keep both fixed.
Mistake: No Plain-Text Fallback
Some inboxes render heavy HTML poorly. Some readers prefer plain text for privacy reasons. Most ESPs generate a plain-text version automatically. It is still worth checking that version reads sensibly, not just assuming it works.
Mistake: Designing Only for Desktop
Most newsletter opens happen on a phone. A layout that only looks right at full desktop width loses readers before they reach the first link. Preview every issue on a narrow screen before you send it, not after a complaint arrives.
Mistake: Treating Every Issue the Same
A newsletter that never varies its format (same length, same number of links, same tone) eventually reads as routine. Vary the structure slightly. Keep the cadence and sender identity fixed. That keeps a newsletter feeling current without breaking the habit you built.
How to Measure a Newsletter’s Performance
Each metric below answers one specific question. Read them together, not alone. A newsletter can look healthy on one number and be failing on another.
Six Metrics Every Newsletter Setup Should Track
- Open rate. The share of delivered emails that were opened. Useful as a trend for one list over time. Less reliable for comparing across lists, since inbox apps handle image loading and privacy proxies differently.
- Click rate. The share of delivered emails that got at least one click. The average across industries is 2.62%, according to Mailchimp’s benchmarks. Treat it as a floor to beat, not a target to stop at.
- Click-to-open rate. Clicks divided by opens. This isolates content quality from subject-line quality. A low number here means the subject line worked, but the content did not deliver on its promise.
- Unsubscribe rate. The share of recipients who opt out per send. The overall average is 0.22% (Mailchimp). A spike after one issue usually points to a content or frequency problem in that send.
- Spam complaint rate. The share of recipients who mark an email as spam. Google’s Postmaster Tools recommend keeping this below 0.3%, ideally under 0.10%. Mailbox providers use it to decide future deliverability for the whole domain.
- List growth rate. New subscribers, minus unsubscribes and bounces, divided by total list size. A newsletter can show a rising open rate while actually shrinking, if nobody tracks growth rate too.
Reading These Numbers Together
Start with spam complaint rate. It is the one metric that can get future emails blocked outright, so treat any reading near 0.3% as urgent. Next, check unsubscribe rate against your own history, not the industry average; a sudden spike points to that specific send.
Finally, compare click-to-open rate issue by issue. A steady open rate with a falling click-to-open rate usually means the subject lines still work, but the content has drifted from what subscribers expect.
The One Decision Rule: Protect Deliverability Before You Chase Growth
If you remember one rule from this guide, make it this one. Never let list growth outrun list health. A newsletter that adds subscribers faster than it can keep its complaint rate under control will eventually hurt every send, including to its oldest, most engaged readers.
Here is an illustrative example, with invented numbers. A newsletter has 10,000 subscribers and a 0.05% complaint rate. It runs a paid growth campaign that adds 40,000 new, cold subscribers in a month. The complaint rate on the new segment rises to 0.4%, above Google’s 0.3% guidance.
Within weeks, open rates drop across the entire list, including the original 10,000, because mailbox providers now treat the whole domain with more suspicion. The fix is to pause growth, remove or re-permission the new segment, and rebuild domain reputation gradually.
A Real Case: How Morning Brew Grew a Newsletter Before It Grew a Business
Morning Brew, the business-news newsletter, did not start with a growth hack. According to its own founder’s account on the Morning Brew Founders Journal podcast, the first 20 subscribers were family members. Friends and classroom pitches at the University of Michigan grew the list to roughly 2,500.
The founder calls reaching 10,000 subscribers the real inflection point. That milestone came through a campus ambassador programme across multiple schools. He describes it as the moment “you can actually start making money off an email newsletter.”
From that base, Morning Brew built a structured referral programme instead of relying on one-off growth pushes. The newsletter has since grown to roughly 4.5 million subscribers. The podcast notes that over 400,000 people have made at least one referral through that programme.
This case is really about sequencing. Morning Brew treated the first 10,000 subscribers as a foundation to earn, not a number to buy, and only built a scalable referral mechanism once engagement at that smaller scale proved the content worked.
Treat this as one documented growth path, not a universal formula. A business newsletter aimed at college students will not translate directly to every niche or audience, and setting out to copy it exactly would miss the point of the sequencing lesson itself.
Frequently Asked Questions About Setting Up Email Newsletters
What is the best way to setup email newsletters from scratch?
Start with a visible, specific signup form and double opt-in. Send an immediate welcome email. Authenticate your sending domain with SPF and DKIM. Then settle on a fixed cadence before you write more than two or three issues.
How often should I send a newsletter?
Choose a frequency you can sustain for months, not the most ambitious one on day one. A consistent weekly or biweekly send that always arrives builds more trust than a daily send that stops after a month. Cadence is one of the first decisions to lock in when you setup email newsletters.
What is a good open rate for an email newsletter?
There is no single good number, because open rate varies by industry, list age and inbox privacy settings. The average across industries is 35.63% (Mailchimp). Use your own list’s history as the real benchmark, and treat the industry figure as a rough reference point.
Do I need double opt-in for my newsletter?
It is strongly recommended for any publicly advertised signup form. Double opt-in removes mistyped and fake addresses before they raise your bounce or complaint rate. That protects deliverability for every subscriber on the list, not just the new ones.
Why is my newsletter going to spam instead of the inbox?
The most common causes are missing SPF/DKIM authentication, a rising spam complaint rate, a sudden spike in sending volume, or a list that was bought rather than built through opt-in. Check your spam complaint rate first. Google recommends keeping it below 0.3%.
Should I buy an email list to start faster?
No. A bought or scraped list has not given permission, so complaint and bounce rates run far higher. The damage to your sending domain’s reputation affects every future email, including to subscribers who opted in properly.
What is the difference between open rate and click-to-open rate?
Open rate measures how many delivered emails were opened. Click-to-open rate measures how many of those opens led to a click. A strong open rate with a weak click-to-open rate usually means the subject line worked, but the content inside did not match what it promised.
Can I setup email newsletters without any budget?
Yes. Most ESPs offer a free tier that covers double opt-in, basic automation and authentication setup for a small list. The permission-building habits in this guide cost time, not money, so a limited budget is rarely the real barrier to a working newsletter.
Start With Permission, Then Build the Habit
If you remember one thing about how to setup email newsletters that last, make it the sequence, not the template. Permission-based list building. Authenticated sending. A cadence you can sustain. Metrics you actually check after each issue.
Get those four right, and the writing has a far better chance of being read. For the audience-side half of this problem, see our guide on building buyer personas, which helps decide what a newsletter should say to the people on that list.
