Developing an email marketing strategy

A results-driven and a well-defined email marketing strategy sets the foundation for successful campaigns that aligns with your business goals and guides your efforts.

Outline goals and target metrics

Be specific with quantitative targets for metrics like open rate, CTR, conversions based on past data and platform averages. Review monthly and adjust accordingly.

Example monthly targets:

  • Open rate: 25%
  • Click rate: 5%
  • Conversion rate: 15%

Identify target audience personas

Create one or more buyer personas representing your ideal customers. Identify their demographics, challenges, motivations and more. Customize email content accordingly.

Map out customer journey

Plot the typical customer journey to understand buyer stages and inform content. For example:

Awareness > Interest > Consideration > Evaluation > Purchase > Retention

Create emails tailored to each lifecycle stage.

Choose email types

Types include:

  • Promotional emails: Offer discounts, new product announcements, or exclusive deals.
  • Educational emails: Share industry insights, provide tips and tutorials, or showcase product features.
  • Transactional emails: Order confirmations, shipping updates, or account notifications.
  • Welcome emails: Greet new subscribers, introduce your brand, and set expectations.
  • Event-triggered
  • Surveys
  • Newsletters

Balance email types based on business model and customer journey.

Set realistic KPIs

Key metrics include:

  • Open rate
  • Clickthrough rate (CTR)
  • Bounce rate
  • Conversion rate
  • Unsubscribe rate

Set realistic benchmarks for optimization using industry data.

Building your email list

Growing a targeted email list is vital for email success.

Explain permission-based email marketing

Legally, you can only send emails to subscribers who opted in to receive communications. Clearly explain how their details will be used.

Methods for collecting email subscribers

Popular list building tactics:

  • Website forms offering lead magnets
  • Website popups or slide-ins
  • Social media and paid ads pointing to opt-in forms
  • Gated content offers in exchange for email
  • Event and webinar sign-ups

Incentivize subscribers and make opting in easy.

Import contacts legally

You can import contacts from your CRM or elsewhere but you still need opt-in consent first. Never purchase lists.

Confirm subscriptions

Use double opt-in with automated confirmation emails to verify willingness, increasing engagement and deliverability.

Email content best practices

Well-crafted emails convert.

Example Email Structure:

Subject Line
Preheader Text
Header Image/Logo
Intro paragraph

  • Include name personalization
    Key content section
  • Images, headers, lists etc
    Call To Action (CTA)
  • Clear motivation
    Footer Text
  • Links, addresses
    Unsubscribe link

Subject lines

Catch attention with urgent or benefit-driven subjects personalized for groups. Avoid spam triggers.


Use first names, location details and past behavior to provide tailored, relevant content.


Easily scannable copy has short paragraphs of 1-3 sentences and bullet points for quick consumption by subscribers.

Email design and layout

A well-designed template effectively conveys your brand and message.

Use mobile-responsive templates

Test renders across devices. Over 50% of emails are opened on mobile.

Focus on key sections

Important areas include header logo, main image, and CTA placement.

Optimize images

Images should visually engage viewers but also maintain fast load times. Use compression tools to reduce image file size for smooth delivery.

Send timing and frequency

When and how often you send communication affects metrics.

Vary timing

Test emails sent on different weekdays and times to determine optimal windows for your audience and avoid spam filters.

Consistent schedules

Regardless of one-off sends, adhere to regular cycles so contacts know when to expect your emails. This builds engagement over time.

Email service providers

Rely on dedicated email marketing platforms for crucial functionality.


Tools like MailChimp, HubSpot, GetResponse seamlessly integrate with CRMs, webinar software, analytics platforms via APIs for powerful autosyncing abilities between systems.

Expand functionality with segments, workflows and automations.

Divide contacts into segments, tailoring sends for each group. Set up workflows and triggers enacting autoresponder streams, re-engagement sequences, etc

Improving inbox placement

Maximize deliverability with proper authentication and engaged list building.

Permission reminders

Periodically reiterate subscription consent and provide easy unsubscribe access. Keep your list clean.

Enable domain authentication

Implement SPF, DKIM and DMARC for sender verification, improving inbox deliverability through confirmed domain ownership and reduced spoofing.

Constant email analytics

Continual analysis using hard metrics fuels optimization. Important KPIS:

  • Open rate: Percentage of total recipients who opened an email
  • Clickthrough rate: Percentage of total recipients who clicked any link
  • Conversion rate: Percentage who completed a desired action
  • Unsubscribe rate: Percentage who opted out from the mailing list

Segment these metrics by campaign, groups and other factors to find successes to replicate and problem areas to improve.

Tips On Email Marketing Best Practices

  1. Get permission before sending emails to people: This means you should have them opt-in to receive emails from you. This can be done through a sign-up form on your website, or by including a checkbox in a purchase process that allows people to opt-in to receive emails. This practice helps ensure that the people you are sending emails to actually want to receive them, which can help improve the effectiveness of your campaigns and reduce the chances of your emails being marked as spam.
  2. Make sure the emails you send are wanted by the recipient: Don't send emails just to send emails. Instead, make sure you have something valuable or relevant to share with your audience. If you are sending emails just to send emails, people are likely to get annoyed and either mark your emails as spam or unsubscribe from your list.
  3. Use a clear and concise subject line: The subject line of your email is the first thing that people see, so it's important to make it compelling and accurate. A good subject line should be no more than 50 characters and should clearly communicate the content of the email.
  4. Use a professional-looking email template: Use an email template that is visually appealing and easy to read. Avoid using large blocks of text, and use headings, bullet points, and images to break up the content and make it easier to scan.
  5. Include an easily visible way for people to unsubscribe: Federal laws require that you include an unsubscribe option in all of your marketing emails. Make sure this option is easy to find and use. This can help prevent people from marking your emails as spam, and it helps ensure that you are only sending emails to people who want to receive them.
  6. Use a “From” name that is recognizable and professional: Use a “From” name that is recognizable and reflects your brand. This can help improve the chances that people will open your emails.
  7. Test your emails on different devices and email clients: Different email clients and devices can display emails differently, so it's important to test your emails to make sure they look good everywhere. You can use tools like Litmus or Email on Acid to test your emails across a range of devices and email clients.
  1. Don't use spam trigger words: There are certain words and phrases that can trigger spam filters, such as “free,” “earn money,” and “win.” Avoid using these words in your subject lines and body copy to reduce the chances that your emails will be marked as spam.
  2. Avoid sending emails to purchased lists of email addresses: It's generally not a good idea to send emails to lists of email addresses that you have purchased. These lists are often low quality and may contain a lot of invalid or inactive email addresses. This can result in a high number of bounces and complaints, which can hurt the deliverability of your emails and damage your sender reputation.
  3. Monitor and analyze the success of your emails: Use email marketing metrics like open rate, click-through rate, and conversion rate to understand how well your emails are performing. Use this information to continuously improve the content and targeting of your emails to make them more effective.


Q: How often should I send emails?

The ideal frequency depends on your audience and business goals. However, it's generally recommended to avoid sending emails too frequently, as this can lead to unsubscribes and decreased engagement. A good rule of thumb is to start with a weekly or bi-weekly schedule and adjust based on your audience's response.

Q: What should I include in my email subject lines?

Subject lines are one of the most important aspects of your email marketing campaigns. They should be concise, relevant, and personalized to entice recipients to open your emails. Use strong verbs, highlight benefits, and avoid spammy language.

Keep your emails as concise as possible while still conveying your message effectively. Aim for a length that is appropriate for your audience and the content you're sharing. Long emails can be overwhelming, while overly short emails may not provide enough value.

Use a consistent and visually appealing design that is easy to read on all devices. Incorporate high-quality images, use clear font styles, and ensure adequate spacing. Make sure your emails are mobile-responsive to adapt seamlessly to different screen sizes.

Q: How can I improve my email deliverability?

Deliverability refers to the ability of your emails to reach subscribers' inboxes. To improve deliverability, maintain a healthy email list, avoid spammy content, and implement authentication protocols like SPF and DKIM.

Q: How can I measure the success of my email marketing campaigns?

There are several key metrics to track to measure the success of your email marketing campaigns, including open rate, click-through rate (CTR), conversion rate, and unsubscribe rate. Use these metrics to identify areas for improvement and optimize your campaigns.

Q: What are some tools and resources for email marketing?

There are numerous email marketing tools and resources available to help you manage your campaigns, track performance, and create effective emails. Popular ESPs (Email Service Providers) include Mailchimp, Constant Contact, Sendinblue, and ActiveCampaign.
