Email Marketing for Small Businesses: Start With 5 Emails

When I bring up email marketing with small business owners in Pakistan and India, the first reaction is usually, "Email? My customers are all on WhatsApp."

Fair. WhatsApp is where the conversations happen. But your email list is something you own. If a platform changes its rules or your number gets blocked, your list is still yours. Email is also where receipts, invoices, bookings and international customers already live.

The mistake beginners make is starting with a monthly newsletter. It's hard to keep up, and most of them die after issue three. So start smaller: five emails that do real work for your business, most of which you write once and reuse. I've done digital marketing for 8 years, and this is the setup I'd give any small business starting from zero. Templates are below, ready to copy.

Before you write anything: 4 quick setup steps

1. Pick a free email tool

You don't need to pay on day one. Here's what the three popular free plans include, going by each company's own pricing and help pages (checked 20 October 2026; these limits change, so double-check before you sign up):

My honest take: if you want the welcome and follow-up emails to send themselves, start with Brevo or MailerLite. If you already use Mailchimp and only need a welcome email, its free plan can still do that.

2. Send from your own domain, not Gmail

Use something like hello@yourbrand.com, not yourbrand123@gmail.com. Mailchimp's page on free email addresses strongly recommends switching to an address on your own domain and explains that free providers' DMARC policies can cause delivery problems. Google's email sender guidelines also require everyone who sends to Gmail to set up SPF or DKIM authentication. Your email tool will walk you through adding these records to your domain. It's usually a one-time job, and if the terms confuse you, I've explained SPF, DKIM and DMARC in plain English.

3. Only email people who said yes

Don't buy lists. Don't add every number from your phone contacts. Don't pre-tick the "send me offers" box at checkout. Both Google and Yahoo say to send only to people who signed up, and both warn against opt-in boxes that are checked by default. Beyond the rules, people who never asked for your emails mark them as spam, and that hurts every email you send after.

4. Make unsubscribing easy

Every marketing email needs a visible unsubscribe link. Your email tool adds one automatically, so don't hide it. Google says every sender should keep spam rates below 0.3%, and bulk senders (more than 5,000 messages a day to Gmail) must also support one-click unsubscribe. Yahoo says unsubscribes should be honoured within 2 days. You're probably nowhere near those volumes, but following the same rules from day one keeps you out of the spam folder.

Where to get your first email addresses

You probably have more chances to collect emails than you think:

• At checkout or on the invoice. "Can I email you the receipt?" works in shops, clinics and service businesses.
• On WhatsApp, after an order. "Aap ka order confirm ho gaya. Receipt aur delivery update email par bhej doon? Apna email bata dein."
• A simple form on your website with one clear reason to join, like early access to new stock.
• A QR code at the counter linking to your signup form.

Whatever you use, tell people what they'll get, for example: "We'll email your receipt, delivery updates and a few offers a month. Unsubscribe any time." Leave the marketing checkbox unticked and let them tick it.

The 5 emails every small business needs

Swap the [brackets] for your details. Keep each email short. If it doesn't fit on a phone screen with one scroll, cut it.

Email 1: The welcome email

When: Right after someone signs up or buys for the first time. Set it up as an automation (or Mailchimp's final welcome email) so it goes out instantly.

Subject line ideas: "Welcome to [Brand], here's what to expect" / "You're in, [First name]"

Hi [First name],

Thanks for joining [Brand]! I'm [your name], and I run the business with [team / my family / a small team in Karachi].

Here's what you'll get from us: [new arrivals / tips / offers], about [2 to 4] emails a month. No spam, promise.

Three things most new customers ask:

• Delivery: [cities, timelines, charges]
• Payment: [COD, bank transfer, cards]
• Help: reply to this email or message us on WhatsApp at [number]

[Optional: Here's [the welcome offer or free guide] you signed up for: [link]]

Talk soon,
[Name]

Tip: Ask a question at the end, like "What made you check us out?" Replies are gold. They tell you exactly what your customers care about, in their own words.

Email 2: The follow-up email

When: Two to three days after delivery or after the service is done. Adjust the timing to your business.

Subject line ideas: "How's your [product] so far?" / "Quick tip for your new [product]"

Hi [First name],

Your [product/service] should be with you by now. I wanted to check everything arrived the way you expected.

One quick tip: [care instruction / how to get the best result / something most people don't know].

If anything isn't right (size, colour, timing), just reply to this email and we'll sort it out.

[Name], [Brand]

Tip: This email catches problems before they turn into one-star reviews. Send it before the review request, never in the same email.

Email 3: The review request email

When: After the customer has had time to actually use what they bought. For most businesses, that's a few days after the follow-up.

Subject line ideas: "Could you do us a small favour?" / "[First name], how did we do?"

Hi [First name],

Thanks again for choosing [Brand]. We're a small business, and honest reviews help other people decide whether to trust us.

If you have a minute, could you leave an honest review on Google? Here's the link:
[your Google review link]

Good or bad, we read every review and reply to every one.

Thank you!
[Name]

Important: Send this to every customer, not only the ones you think are happy. Google's content policy doesn't allow businesses to offer incentives for reviews, to discourage negative reviews, or to selectively ask happy customers. So no "10% off for a 5-star review", and no "were you happy?" filter that only sends happy people to Google. I cover the full system in how to get more Google reviews without breaking Google's rules, and if your customers prefer WhatsApp, use my WhatsApp templates to ask for Google reviews instead.

Email 4: The win-back email

When: When a customer hasn't bought in a while. "A while" depends on what you sell. For a café it might be a month; for a clothing brand, a season. Pick a number that's longer than your usual repeat cycle.

Subject line ideas: "It's been a while, [First name]" / "We've added a few things since your last visit"

Hi [First name],

It's been a little while since your last order, so I wanted to show you what's new: [2 to 3 new products, services or improvements, with links].

If something didn't go well last time, I'd honestly like to know. Just hit reply.

And if you'd rather not hear from us anymore, no hard feelings. You can unsubscribe with the link below.

[Name]

Tip: That last line isn't just polite. Google's guidelines suggest occasionally checking that people still want your emails and considering removing people who never open them. A smaller list of people who care beats a big list of people who ignore you.

Email 5: The offer email

When: When you have a genuine reason: a seasonal sale, Eid, Diwali, a new launch, clearing old stock, or an anniversary.

Subject line ideas: "[Offer] until [day]" / "Eid collection: early access for our email list"

Hi [First name],

[The offer in one sentence: what they get, for how much, until when.]

Why now: [real reason: new collection, festival, last few pieces].

[Button: Shop now / Book your slot / Message us on WhatsApp]

The offer ends on [date]. After that, prices go back to normal.

[Name]

Tip: Only use a deadline if it's real, and keep promotions out of your receipts and order confirmations. Google's sender guidelines specifically say not to mix different types of content, like promotions inside sales receipts.

Write them faster with AI (but edit them yourself)

You can draft all five emails in one sitting with ChatGPT, Gemini or Claude. Give it context first:

I run [business] in [city]. My customers are [who they are].
My tone is [friendly, simple English with a little Roman Urdu].
Our delivery/payment/returns details: [paste].

Write 5 short emails for my email list:
1. a welcome email
2. a follow-up email 3 days after delivery
3. a Google review request that asks for an honest review
   (no incentives, sent to every customer)
4. a win-back email for customers who haven't bought in [X] months
5. an offer email for [offer, price, deadline]

Each under 120 words, with 2 subject line options.
No words like "elevate", "unlock" or "exclusive VIP".
Don't invent offers, prices or claims I haven't given you.

Then read every email out loud and fix anything you wouldn't say to a customer face to face. My 25 ChatGPT prompts for social media managers show the same "brand brief first" approach for social posts.

Email and WhatsApp: who does what

You don't have to choose. Use each channel for what it's good at:

If you're getting chats from ads, my click-to-WhatsApp ads guide covers the chat side. Once those chats become customers, these five emails help bring them back.

If you sell through an online store, add one more automated email once these five are running: a reminder for people who leave checkout without ordering. Here's my guide to abandoned cart emails, with timing and templates for Shopify and Klaviyo.

And if some of your customers rarely open email, short order updates and the occasional offer by text can fill the gap. I've covered the rules and templates in my guide to SMS marketing in Pakistan with branded (masked) SMS.

What to measure

Keep it to four numbers per email: clicks, replies, unsubscribes and sales you can trace. Don't obsess over open rates. Google's sender guidelines say Google doesn't track open rates, can't verify open rates reported by third parties, and that low open rates aren't necessarily a sign of a deliverability problem.

If unsubscribes jump after an email, you either sent too often or sent something people didn't expect when they signed up.

Mistakes to avoid

• Sending from a Gmail or Yahoo address instead of your own domain
• Adding people who never signed up, or buying a list
• Starting with a newsletter you can't keep up with
• Asking for reviews only from happy customers, or offering a discount for them
• Fake deadlines and "last chance" emails every week
• Writing long emails that need three scrolls on a phone
• Hiding the unsubscribe link

Once these five emails are running, you need people to send them to. Short videos are one of the easiest ways for a small brand to get noticed, and I've written a phone-only short-form video workflow you can run without a team. If reviews are a priority for you, my online reputation management routine fits right next to email 3.

FAQ

What emails should a small business send first?

Start with five: a welcome email when someone signs up or buys, a follow-up a few days after delivery, a review request, a win-back email for customers who haven't bought in a while, and an offer email when you have a genuine reason to run a promotion.

Which free email marketing tool is best for beginners?

If you want automated welcome and follow-up emails, Brevo and MailerLite both include automations on their free plans. Mailchimp's free plan covers up to 250 contacts and 500 sends a month but doesn't include automation flows, apart from a final welcome email for signup forms.

Can I send marketing emails from a Gmail address?

You can, but it's not a good idea. Mailchimp strongly recommends using an address on your own domain because free email providers' DMARC policies can cause delivery problems, and Google requires everyone sending to Gmail to set up SPF or DKIM, which you can only do on a domain you own.

How many emails can I send on a free plan?

It depends on the tool. As of October 2026, Mailchimp Free allows 500 sends a month with a daily limit of 250, Brevo Free allows 300 emails a day, and MailerLite Free allows 2,500 emails a month for up to 250 subscribers. Check each tool's pricing page, because limits change.

Do I need permission to email my customers?

Yes, treat permission as a must. Google and Yahoo both say to send email only to people who signed up to hear from you and to avoid opt-in boxes that are ticked by default. People who didn't ask for your emails are more likely to mark them as spam, which hurts your delivery.

Can I offer a discount in exchange for a Google review?

No. Google's Maps content policy doesn't allow businesses to offer incentives such as payment, discounts or free goods in exchange for reviews, or to ask only happy customers. Ask every customer for an honest review the same way, with no reward attached.
