How to Start Email Marketing for Your Business: A First-Month Plan

You’ve been meaning to start a newsletter for 2 years. You have a list of customer emails in a spreadsheet, a vague idea of sending “updates” and no clue where to begin. Meanwhile, the businesses down the street fill their slow Tuesdays with a single email.

Email remains one of the few marketing channels you fully own. No algorithm decides whether your customers see your post. If someone signed up, your message lands in their inbox, as long as you set things up correctly.

This guide gives you a 4-week plan: choose a platform, set up your sending domain, build a compliant list and send your first 3 campaigns. No marketing degree required.

What you need before you send anything

You need 4 things in place:

1. An email marketing platform (also called an email service provider, or ESP)
2. A sending address on your own domain, like hello@yourbusiness.com, not a free Gmail or Yahoo address
3. A list of people who agreed to receive your emails
4. A plan for what you’ll send and how often

Week 1 covers the first 2. Week 2 covers the list. Weeks 3 and 4 are for sending.

Week 1: Choose a platform and set up your domain

Pick an email marketing platform

Don’t send marketing emails from your regular inbox. Email marketing platforms handle unsubscribes, templates, list management, sign-up forms and reporting, and they help you follow the rules automatically.

Common options include Mailchimp, Constant Contact, Klaviyo, Brevo, MailerLite and the email tools built into many CRMs and ecommerce platforms. Several offer free or low-cost plans for small lists. Pricing usually scales with the number of contacts or emails sent.

What to look for	Why it matters
Easy drag-and-drop editor	You’ll actually send emails if it’s quick
Sign-up forms and pop-ups	You need a way to grow the list
Automations (welcome series, birthday emails)	Set-and-forget emails that keep working
Integrations with your store, POS or CRM	Keeps your list updated automatically
Domain authentication support	Required for good deliverability
Clear pricing as your list grows	Avoids surprise bills

If you already use a CRM, check whether it includes email marketing before buying a separate tool. See what is a CRM for how the 2 fit together.

Authenticate your sending domain

This step is technical, but it’s the difference between landing in the inbox and landing in spam. Your platform will walk you through adding a few DNS records to your domain:

• SPF lists which services may send email for your domain.
• DKIM adds a digital signature that proves the email wasn’t altered.
• DMARC tells inbox providers what to do with mail that fails those checks.

Since February 1, 2024, Google requires all senders to Gmail accounts to set up SPF or DKIM, and bulk senders (close to 5,000 or more messages a day to personal Gmail accounts) must set up SPF, DKIM and DMARC. Microsoft introduced similar requirements for high-volume senders to Outlook.com, Hotmail and Live addresses in 2025. Even if you’re far below those volumes, set up all 3. Our guide on SPF, DKIM and DMARC explains each in plain English.

Week 2: Build a clean, legal starting list

Start with people who asked

Your best first list is customers and contacts who have given permission: people who signed up on your website, opted in at checkout or asked to join at an event.

Never buy an email list. Purchased lists produce spam complaints, which damage your sender reputation. Google asks senders to keep spam rates reported in Postmaster Tools below 0.3% and ideally below 0.1%. A bought list can blow past that in one send.

If you have an old spreadsheet of past customers who never explicitly opted in, consider a one-time permission email asking them to confirm they want to hear from you, and only add those who say yes.

Follow CAN-SPAM

In the US, commercial email is governed by the CAN-SPAM Act, enforced by the FTC. The main requirements:

• Don’t use false or misleading header information or subject lines.
• Identify the message as an ad when it is one.
• Include a valid physical postal address.
• Give a clear way to opt out, and honor opt-outs within 10 business days.
• Monitor anyone who sends email on your behalf. You’re still responsible.

The law applies to business-to-business email too. Each violating email can bring significant penalties under the FTC’s guidance. Your email platform handles the unsubscribe link and footer, but you’re responsible for your content. Google also recommends processing unsubscribe requests within 48 hours, which is a good standard to follow. This is not legal advice.

Add a signup form

Add a simple form to your website, ideally in the footer and on a dedicated page. Offer a clear reason to join, such as “Monthly tips and first look at new products.” For more ideas, read how to build an email list from scratch.

Key takeaway: A small list of people who asked to hear from you beats a big list of strangers. Permission, authentication and a working unsubscribe link protect your deliverability and keep you on the right side of CAN-SPAM.

Week 3: Send your first 2 campaigns

Campaign 1: The welcome email

Set this up as an automation so every new subscriber gets it right away. Keep it short:

• Thank them for joining.
• Say what you’ll send and how often.
• Give one useful thing: a tip, a guide or a small first-time offer.
• Add one clear button, like “Book your first visit” or “Shop new arrivals.”

The welcome email reaches people at the moment they’re most interested, because they just asked to hear from you. Make it count.

Campaign 2: A helpful update

Send this to your whole list. Make it genuinely useful, not just promotional:

• A seasonal tip related to your service (“3 things to check before winter”).
• A behind-the-scenes look at a new product or team member.
• An answer to the question customers ask you most.

Keep it to 1 main topic, a short intro, 2 to 4 short paragraphs or bullets and 1 call to action. Write a subject line that says what’s inside. “Your furnace checklist for October” beats “October newsletter.”

Week 4: Send an offer and review results

Campaign 3: A simple offer

Now that subscribers have heard from you twice, send a clear offer: a limited-time discount, a free add-on, early booking for a busy season or a new product launch. Be specific about what, how long and how to claim it. Don’t invent fake deadlines, since misleading claims can create problems with customers and regulators.

Review your numbers

After each campaign, check:

Metric	What it tells you	What to do if it’s weak
Delivery rate	Did emails reach inboxes at all?	Recheck authentication; clean bad addresses
Open rate	Did the subject line and sender name work?	Test clearer subject lines. Treat opens as a rough signal, since privacy features can inflate them
Click rate	Was the content useful and the button clear?	Use one main call to action
Unsubscribe rate	Is the frequency or content off?	Ask subscribers what they want
Spam complaints	Are people surprised to get your email?	Confirm permission; remind them why they’re receiving it
Sales or bookings	Did email drive revenue?	Use tracked links or offer codes

Spam complaints matter most. Keep them as close to zero as you can.

Setting a sending rhythm

For most small businesses, 2 to 4 emails a month is a sustainable start. Consistency matters more than frequency. Pick a day, put it on the calendar and stick to it for 3 months before changing anything.

Build a simple content calendar with 3 recurring types:

• Helpful: tips, how-tos, answers to common questions
• Story: new products, team news, customer spotlights (with permission)
• Offer: promotions, seasonal deals, events

Rotate them so subscribers don’t feel sold to every time.

Where to start today

1. Choose an email platform and create an account.
2. Set up your sending address on your own domain and add SPF, DKIM and DMARC records.
3. Add a signup form to your website.
4. Import only contacts who opted in.
5. Build and turn on your welcome email automation.
6. Schedule your first helpful update for next week.
7. Put a monthly offer on the calendar.

Conclusion

Starting email marketing is mostly about doing a few basics right. Use a real email platform, authenticate your domain, build a list of people who asked to hear from you and follow CAN-SPAM. Then send 3 campaigns in your first month: a welcome email, a helpful update and an offer. Review the numbers, keep a steady rhythm and improve one thing at a time.
