If you run a small business and you’re only sending emails when you have something to sell, you’re leaving money on the table every single week. Email is not just a promotional channel. It’s a relationship channel. And the businesses that treat it that way are the ones building audiences that actually buy.
The average email open rate across all industries hovers around 21-23%, according to Mailchimp’s latest benchmarks. But businesses that send the right mix of emails consistently see open rates north of 35-40% because their subscribers expect to hear from them and look forward to it.
Here are the five emails every small business should have running. Some are automated. Some are manual. All of them do real work.
1. The Welcome Email
This is the most important email you will ever send. Bar none.
When someone signs up for your list, they’re at peak interest. They just found you, they just raised their hand, and they’re waiting to see what you do with that. The welcome email is your first impression, your handshake, and your chance to set expectations.
Most businesses send a generic “Thanks for signing up!” message and call it a day. That’s a missed opportunity worth measuring in dollars.
A strong welcome email does three things:
- Delivers on the promise that got them to subscribe (a freebie, a discount, an intro piece of content)
- Sets expectations for what they’ll receive and how often
- Makes a first ask that’s easy to say yes to (reply with a question, click this link, watch this video)
Real subject line examples that work: “Here’s your free guide (plus what to expect from us)” or “You’re in. Here’s what happens next.”
Welcome emails average 4x the open rate and 5x the click rate of standard marketing emails. If yours is weak, fix it before anything else.
2. The Nurture Sequence
After the welcome email, most businesses go silent until they have something to sell. That’s the wrong move.
A nurture sequence is a series of 3-6 automated emails that run in the days and weeks after someone joins your list. The purpose is simple: build trust before you ask for a sale.
Here’s a structure that works for most service-based businesses:
- Email 2 (Day 2): Your story. Why you do what you do. This is where you build connection.
- Email 3 (Day 4): A valuable tip, case study, or how-to that proves your expertise.
- Email 4 (Day 7): Social proof. A client win, a testimonial, or a before-and-after.
- Email 5 (Day 10): A soft pitch. Here’s what we offer. Here’s who it’s for. No pressure.
- Email 6 (Day 14): A direct offer with urgency or a limited-time angle.
By the time Email 6 lands, your subscriber has heard from you six times, learned something useful, and seen proof that you deliver results. That’s a very different conversation than cold pitching someone who doesn’t know you.

3. The Broadcast Newsletter
Automated sequences do the heavy lifting early. Broadcast newsletters are what keep your list warm over time.
A broadcast is a one-time email you send to your entire list (or a segment of it) manually. It could be weekly, biweekly, or whenever you have something worth saying. The goal is to stay top of mind without being annoying.
The best broadcast newsletters have one thing in common: they give before they ask. Share a useful tip, a behind-the-scenes story, an industry insight, or a personal update. Then, if it’s relevant, include an offer or a link to something you’re selling.
Subject lines that consistently perform well for broadcast emails:
- “What I learned from [client story or mistake]”
- “The [industry] advice that actually works in 2026”
- “Quick question for you”
- “This is what [X] looks like when done right”
Aim for 80% value and 20% promotion as a rough guide. Your subscribers will stay subscribed longer and convert at a higher rate than a list you only hit with sales pitches.
4. The Re-Engagement Email
Every email list gets cold over time. People sign up, life happens, and they stop opening your emails. A re-engagement campaign is how you bring them back or clean them out so your deliverability doesn’t suffer.
Typical re-engagement trigger: subscribers who haven’t opened an email in 60-90 days.
The re-engagement sequence usually runs 2-3 emails:
- Email 1: A pattern interrupt. Subject line like “Did we lose you?” or “It’s been a while. We miss you.” Remind them of the value they signed up for.
- Email 2 (3-5 days later): Offer an incentive. A discount, a free resource, an exclusive piece of content. Give them a reason to come back.
- Email 3 (5 days later): The breakup email. “We’re going to remove you from our list in 48 hours unless you click here.” This one gets surprisingly high engagement because people don’t want to feel like they’re missing out.
Re-engagement campaigns typically recover 3-10% of cold subscribers. That sounds small, but on a list of 5,000 cold contacts, that’s 150-500 re-engaged buyers who already know who you are. We break down the full strategy in our post on re-engaging cold subscribers with the win-back email.
5. The Post-Purchase Email
Most businesses treat a completed sale as the end of the email conversation. The smarter ones treat it as the beginning of a longer one.
The post-purchase email (or sequence) is your opportunity to confirm the buying decision, deliver a great experience, and set up the next sale before the customer has even had time to miss you.
A simple post-purchase sequence for a product or service business:
- Email 1 (Immediate): Confirmation + what happens next. Reduce buyer’s remorse immediately. Tell them exactly what to expect.
- Email 2 (Day 3): Check in. How’s it going? Do they have questions? This is also where you surface support resources.
- Email 3 (Day 7-14): Ask for a review or testimonial. Strike while the experience is fresh and positive.
- Email 4 (Day 21-30): Cross-sell or upsell. Based on what they bought, what’s the logical next step?
Post-purchase emails have some of the highest open rates in email marketing, often hitting 50-70%, because customers are engaged and paying attention. Use that window. A strong customer experience here is also one of the best drivers of repeat business, which we cover in depth in our guide to turning one-time customers into repeat buyers.
Getting the Mechanics Right
None of these emails work if they’re landing in the spam folder. Before you build out any of these sequences, make sure your sending domain has SPF, DKIM, and DMARC records set up. Use a reputable platform like Mailchimp, Klaviyo, or ActiveCampaign. Keep your list clean by suppressing hard bounces and unengaged contacts.
If you’re hiring a copywriter to help write these sequences, Fiverr has solid email copywriters at every budget, from $50 per email up to $500+ for high-conversion sales sequences. Just look for sellers with verified reviews in email marketing specifically and request samples before committing.
Start With One
If you don’t have any of these running yet, don’t try to build all five at once. Start with the welcome email. Get that dialed in. Then add the nurture sequence. Then a regular broadcast cadence. Layer in re-engagement and post-purchase as your list grows.
Email marketing compounds. A list of 1,000 engaged subscribers who know and trust you will outperform a list of 10,000 people who barely remember signing up. Build the right way from the start.
