Email marketing consistently delivers one of the highest returns of any digital channel, yet many businesses launch campaigns without a clear plan and wonder why results are disappointing. Email marketing campaigns have an average ROI of 36 times, meaning businesses earn $36 for every dollar spent. The gap between brands that capture that return and those that don't almost always comes down to the fundamentals: a defined goal, a quality list, the right platform, and consistent execution. This guide walks you through every step needed to start an email marketing campaign that delivers real, measurable results.
Key Takeaways
For every $1 spent on email marketing, businesses see an average return of $36, a 3,600% ROI.
Building a permission-based list from the start protects your sender reputation and your deliverability.
Email automations deliver 30 times more revenue per recipient than one-off campaigns, with automated flows earning $1.94 per recipient versus $0.11 for standard sends.
Segmenting your audience before you write a single email increases relevance and lifts performance significantly.
Brands that regularly A/B test their emails achieve 83% higher ROI than those that never test.
Step 1: Define Your Goal Before You Write Anything
Before you think about content or design, you need to define the objectives of your campaign. Having clear, specific goals ensures your campaign has direction and purpose.
Campaigns without goals produce data without meaning. You cannot improve what you have not decided to measure.
Common campaign goals include:
Growing your subscriber list to a specific number
Driving traffic to a product page or blog post
Generating a set number of qualified leads per month
Increasing repeat purchases from existing customers
Onboarding new users and reducing churn
An email marketing strategy is the overarching plan for your campaign. It should include not only your methods, objectives, and analysis, but also what you're aiming for, why you're aiming for it, and how you will measure success.
Make your goal specific and time-bound. "Increase revenue" is not a goal. "Generate 200 trial signups in 30 days using a 5-email nurture sequence" is.

Step 2: Know Your Audience
If you want to reach customers through email, the first step is understanding who they are. Getting to know your customers is important because it allows you to create relevant content for your emails.
Build a basic audience profile before anything else. Document:
Demographics: age, location, job title, industry
Pain points they are actively trying to solve
Where they are in the buying journey (awareness, consideration, decision)
What they have already responded to from your brand or competitors
43% of consumers will unsubscribe from your email marketing if the messages are not relevant. Audience clarity is not a nice-to-have. It determines whether people stay on your list or leave it.
Step 3: Choose an Email Service Provider
Your email service provider (ESP) handles list management, sending infrastructure, automation, and analytics. The right choice depends on your list size, budget, technical needs, and the types of emails you plan to send.
Key features to evaluate:
List segmentation and tagging
Automation and behavioral triggers
A/B testing capability
Deliverability track record
Analytics and reporting depth
Integration with your CRM or e-commerce platform
When selecting an ESP, prioritize ones with a proven track record in maintaining high deliverability rates. Look for features such as robust authentication protocols, dedicated IP options, and comprehensive analytics to monitor and improve sender reputation.
Popular platforms include Mailchimp, Klaviyo, ActiveCampaign, and ConvertKit. Each serves different use cases. E-commerce brands often benefit from Klaviyo's behavioral data depth; content businesses often start with ConvertKit or Mailchimp. For a detailed platform comparison, see our guide on email marketing strategy templates.
Step 4: Build a Permission-Based Email List
This is where many new senders make their first serious mistake: purchasing a list. Purchased lists contain users who did not opt in to receive your messaging and who are not expecting to hear from your brand. As a result, they are more likely to ignore your messages, unsubscribe, or mark your messages as spam.
Build your list organically using:
Lead magnets: A lead magnet is a free resource you offer in exchange for an email address. Effective lead magnets solve a specific, immediate problem for your target audience. They deliver a quick win, something the reader can apply right away to see a tangible result.
High-converting lead magnet formats include checklists, templates, short email courses, calculators, and exclusive discounts. Interactive lead magnets like quizzes and calculators now convert 70% better than static PDFs.
Signup forms: Add clear, simple sign-up forms to your website and promote them on your social channels. Keep them simple, easy to fill out, and not requiring too much information. Offer something of value in return for subscribing, like an exclusive guide, discount, or early access to sales.
Segmentation is the single biggest lever most new email marketers ignore. Sending the same message to every subscriber on your list is a fast route to unsubscribes and low engagement.
Campaigns are usually targeted to a specific audience segment rather than your entire list. Even basic segmentation by signup source, buyer status, or expressed interest will outperform one-size-fits-all broadcasts.
Practical segmentation categories to start with:
New subscribers vs. existing customers
Leads vs. paying customers
Product category interest (if e-commerce)
Engagement level (opens/clicks in the last 90 days)
Location or industry (for B2B senders)
For a deeper look at how segmentation drives revenue, our article on email list segmentation strategies covers the data and practical approaches in detail.
Step 6: Plan Your Campaign Type and Sequence
Not all email campaigns work the same way. Before writing copy, decide what type of campaign you are launching.
Broadcast campaigns go to a segment of your list on a set date. These include promotions, newsletters, and product announcements.
Automated sequences trigger based on subscriber behavior. Despite representing only 2% of email volume, automated messages generated 37% of all email-attributed sales in 2024.
The most important automated sequence to set up first is your welcome series. The top 8% of email programs, those hitting 45:1 ROI or more, most commonly send newsletters and onboarding emails, not promotions. A strong welcome sequence sets expectations, builds trust, and drives early engagement before you ever send a promotional message. See our welcome email sequence best practices for specific frameworks.
Other high-value automation types:
Abandoned cart (for e-commerce)
Post-purchase follow-up
Re-engagement for inactive subscribers
Lead nurture sequences for new signups
Step 7: Write Emails That Get Opened and Clicked
Every email has three jobs: get opened, get read, and get clicked. Each requires a different element.
Subject lines determine opens. The subject line is crucial in getting people to open and click on your emails. Like the headline on a blog post, an email subject line has to get attention so people want to go further. You only have a few words to make an impression. For tested tactics that improve open rates, see our guide to email subject line best practices.
Body copy determines read-through. Keep paragraphs short. Write in second person ("you") and address one idea per email. Match the tone to your audience.
CTAs determine clicks. Every email is a chance to drive your audience toward a goal, whether that's making a purchase, signing up for an event, or simply visiting your website. By including clear calls-to-action in your emails, you guide your readers step-by-step through the customer journey.
One email, one primary CTA. Multiple competing calls-to-action reduce conversions.
Also consider mobile rendering. 50% of people will delete an email if it is not optimized for mobile.
Step 8: Protect Your Deliverability
Your campaign cannot perform if it does not reach the inbox. Only 83.5% of emails globally reach inboxes, meaning one in six emails sent may never be seen. Deliverability is not automatic; it requires active management.
The three pillars of strong deliverability:
Authentication: Authentication protocols (SPF, DKIM, and DMARC) add layers of security, contributing to a positive sender reputation. Set all three up before you send a single campaign.
List hygiene: Practice good email list hygiene by regularly removing inactive, bounced, and other non-engaging email addresses from your lists. Periodically removing unengaged users can improve your sender reputation, reduce the likelihood of landing on an email deny list, and increase engagement rates.
Consistent sending: Mailbox providers consider email volume and send frequency to assess whether an email sender might be engaging in spammy practices. Establish a predictable cadence and stick to it rather than sending in irregular bursts.
A good benchmark to aim for: a good email deliverability rate should be at least 85%. A rate of 98 to 99% is ideal.
Step 9: Test, Measure, and Improve
Measuring your campaign's performance helps you understand what works and what does not. It also gives you insight into how your audience interacts with your brand, helping you adjust your strategy and maximize the impact of future campaigns.
Core metrics to track from day one:
Open rate: Benchmark varies by industry, but overall email engagement improved in 2024, with open rates at 26.6%.
Click-through rate (CTR): In 2024, the average marketing email click-through rate was 2.62%.
Conversion rate: The percentage of recipients who completed your desired action.
Unsubscribe rate: A high rate signals irrelevant content or too-high frequency.
Revenue per email: The most direct measure of campaign value.
Bot-driven phantom engagement has made open rates unreliable, pushing high-performing teams toward revenue per email, list churn, and lifetime value as the metrics that matter.
Run A/B tests on subject lines, send times, CTA copy, and email length. Start with one variable per test and run it long enough to reach statistical significance. For a full framework on tracking and acting on your email data, see our guide on email marketing analytics best practices.
Frequently Asked Questions
How long does it take to see results from an email marketing campaign?
Most brands see measurable engagement (opens, clicks) within the first send. Revenue results depend on your list size, campaign type, and offer. Automated sequences like welcome and abandoned cart flows typically show results within the first two to four weeks. Broadcast newsletters may take two to three months of consistent sending before benchmarks stabilize.
Do I need a large email list to start an email marketing campaign?
No. With a bigger list, you can use the scalability of email marketing. Email scales like crazy and the cost per extra email sent is tiny, so the ratio becomes more attractive as lists and customers grow. But a small, engaged list of 500 subscribers consistently outperforms a large, disengaged list of 50,000. Focus on quality and relevance from the start.
What is the best sending frequency for a new email marketing campaign?
There is no universal answer, but consistency matters more than volume. Test frequency by sending weekly, bi-weekly, and monthly, and keep an eye on unsubscribe rates and other metrics to see whether you are sending too much. A weekly or bi-weekly cadence works well for most new senders while you build your content muscle and monitor engagement signals.
What regulations do I need to follow when starting an email marketing campaign?
In the US, the CAN-SPAM Act requires you to include a physical address, a clear unsubscribe mechanism, and accurate sender information in every commercial email. If you have subscribers in the European Union, the GDPR requires explicit opt-in consent before sending. Canada's CASL has similar requirements. Always use a reputable ESP that supports compliant unsubscribe handling, and only email people who have actively opted in to receive your messages.
