5 Top Types of Email Marketing That Get Replies (With Writing Tips)

An open red mailbox with multiple hand-drawn email envelopes flying away from it, illustrating different types of email marketing.

Some types of email marketing work better for achieving certain business goals than others.

For instance, a regular e-newsletter is ideal for sharing company news and blogs. Outside of a newsletter, to plug an event, a promotional email or “drip” campaign can build interest weeks ahead.

Based on 2024-2025 data compiled by Perplexity, these are the most common types of marketing emails service providers send.

1. Educational Emails: Newsletters That Inform and Promote

What they are: Thought-leadership content:

  • news
  • reviews
  • tips
  • blog posts
  • guides
  • case studies

Subject line example: How to improve your business’s online security.

Stats:

Newsletter example: Calm’s monthly Calm Down newsletter

Writing Tip: Break up text for scannability. Use bullet points, subheadings, or short paragraphs for quicker reading:

✅ Write clear, specific headlines. Summarize the key takeaway.
✅ Keep sentences short — 12-15 words max.
✅ Summarize content and link to the full article.

2. Promotional Emails: Writing That Sells

What they are: Emails that feature product or service sales, discounts, or events; product launches (drip campaigns/automated emails).

Subject line example: Get 25% off your next purchase!

Stats (from Sender):

  • 75 percent of marketers send emails highlighting specific products or features.
  • 72 percent send sales or promotional emails.
  • 71 percent send event announcements.

Email Example: Calm’s 50-percent off a one-year subscription

Writing Tip: Lead with benefits, not features: don’t describe; persuade in concrete language that “shows,” rather than “tells”:

❌ Our latest software update is here!
✅ Save time with our automated productivity tools!

3. Transactional/Behavioral Emails: Writing That Confirms

What they are: Order confirmations, loyalty rewards, password resets, abandoned cart, or appointment reminders.

Transactional emails are more personalized, sent in response to a user’s action. They often focus more on customer service, though they can sell subtly.

Except for product or e-commerce offers like courses, professional service firms rarely use them.

Stats:

  • Automated emails account for 46.9 percent of email sales (Omnisend).
  • Most transactional emails have an average open rate of 80-85 percent. They tend to be higher because people view them immediately or revisit them (Mailgun).

Email Example: RocketLawyer’s nudge to finish completing a bill of sale.

Writing Tips:

✔ Make every word count. Use clear, concise language to help users get the message quickly: “Your order has shipped!” versus “We wanted to let you know your shipment is on its way.”
✔ Use the recipient’s name.
✔ Add subtle cross-sells (e.g., “Need help with more legal documents? Explore our custom estate plans.”).

4. Relationship-Building Emails: Writing That Connects

What they are: Client success stories, holiday greetings, customer appreciation, or welcome emails designed to strengthen bonds.

Example: “Thanks for being a loyal client! Here’s a small token of appreciation.”

Stats:

  • 79 percent of marketers use welcome emails, and 62 percent use onboarding or “post-purchase” emails. (Sender)
  • Welcome emails achieve an average open rate of 83.63 percent (GetResponse).

Writing Tip: Add personality, yet write in your brand’s voice: “Hi, [Name]! We’re thrilled to have you — here’s what you can expect in your inbox.”

5. Survey and Feedback Emails: Writing To Request Information

What they are: Customer satisfaction surveys, net promoter score surveys to measure loyalty, or open-ended questions.

Example: “We’d love your feedback — share your thoughts and help others!”

Stats: The average email survey response rate is roughly 24.8 percent. (FluidSurveys).

Email Example: LegalZoom’s simple survey reminder.

Writing Tips: Keep it concise. Data suggests that if a respondent starts answering a survey, drop-off rates increase sharply with each extra question (up to 15). (SurveyMonkey)

Make it easy and enticing.

  • Easy: Use simple, conversational language and provide a clear call-to-action like “Take our 1-minute survey here!”
  • Enticing: Show a benefit, like “Help us improve to serve you better.” Adding a small incentive (e.g., a discount or giveaway) can also boost responses.

With shifting social media rules, algorithms, and ownership, more businesses are focusing on emails. Why? Regardless of your email platform, you own your subscriber list and can take it anywhere. And especially if your emails are set up properly and well-written, you have more control over who gets your messages.

Now that you know the top types of email marketing, once you have subscribers, don’t procrastinate — start creating! See how your emails can spark interest in your products and services.

5 Business Newsletter Writing Best Practices

When you make e-newsletters, which I’ve done for more than ten years, you can overlook some business newsletter writing best practices. Some, like privacy rules, require legal compliance. Others, like the format, can affect a newsletter’s overall impact.

Follow these steps to create emails that comply with commonly accepted standards and build engagement.

See these videos for a more in-depth view of each step described in this blog.

1. Have a plan – Studies show people read online content in an F-shape. They focus on the top and the left side, reading from left to right.

A yellow-ish red eye with a red circle and points around it. Eye-tracking studies show that people read online content in an F-shaped pattern; considering this in your content creation is among the business newsletter writing best practices.

They also tend to scan or skim emails. As email marketer Des Brown suggests, when you create an e-newsletter, consider:

  • scannability
  • visual hierarchy
  • reading patterns

Structure your content accordingly.

Many email marketing platforms offer mobile-friendly templates you can adapt to your style. Especially if you’ve never created an e-newsletter, compiling one is like guesswork. See what to add and where for prime engagement with The Easy 5-Step Business E-Newsletter Template.

2. Consider the format – Beyond planning and structure, a regular format eases creation.

Service provider e-newsletters often start with a “welcome” message, followed by one or two main articles, and then end with an offer. One section usually features a blog.

The listicle format has helped me keep creating e-newsletters for 11 years. Sticking to five key points saves me time, preventing me from driving down dead ends. 

3. Foster ideas – I love to pre-crastinate, gradually adding ingredients to my pot of soup. I log ideas or snippets whenever inspiration strikes. 

Whether you use an online scheduler or a spreadsheet, a three to 12-month content calendar can keep you organized. Apps may remind you about deadlines.

As you consider topics, explore how to save time and how your emails fit into your overall marketing strategy: 

  • Curate content from sources like industry news websites using tools.
  • Reduce, reuse, and recycle: Reinvent any existing content (blog posts, video, press releases, white papers, etc.). Link back, summarize, or rephrase. 

4. Catchier content – Most e-newsletters are educational, selling more subtly than email marketing campaigns. 

Eye-catching headlines, body copy, and calls to action are crucial. The subject line is the first thing people see and influences whether they will open an email.

Example: How to protect, preserve, and pass on your wealth by design (Sundvick Legacy Center)

Content that engages is not only useful or persuasive, but relatable. Sharing your stories in your own voice, like what works and what hasn’t worked for you, shows you as a person, not a bot. Your unique experiences help you stand out.

5. Privacy compliance This is an important business newsletter writing best practice. During a recent e-newsletter review, I was surprised at least ten percent of the U.S. companies’ footers didn’t follow CAN-SPAM rules. Some had “unsubscribe” links in low-contrast colors, making them hard to see.

Other CAN-SPAM aspects to note for commercial emails:

  • identify ads
  • don’t use deceptive subject lines

CASL (Canadian Anti-Spam Law) and GDPR (General Data Protection Regulation; Europe) require similar compliance.

“Create a questionnaire of common information you need to know from clients to put together an e-newsletter. Also, have a template where you can fill in the blanks of what they can discuss, depending on the type of newsletter (sale vs. announcement vs. new service, etc.). Organization and planning can help make the writing process go smoother and faster.”

Healthcare Email Marketing: Best E-Newsletters

In my newsletter, I discussed the aspects of effective emails — check out these examples that follow healthcare email marketing best practices, with good design and writing.

DISCLAIMER: I’m not affiliated with any of these sites. I like their content, and present it for educational purposes only for better healthcare email marketing.

1. MaineGeneral HealtheMatters – They present their information in a visually appealing way while projecting a positive image of their organization to build trust to keep patients and get donations. Donors can give money with one simple, easy-to-find click.

2. MaineHealth Health Matters e-Newsletter – MaineHealth’s engaging e-newsletter truly informs, with healthful recipes, links to health tips and videos, and news everyone can use.

3. Consumers for Affordable Health Care (CAHC) – The weekly Coffee CAHC e-newsletter covers federal and state policy news about health care.  It’s distressing, though, how much it has become politicized and how divisive the issue of access to affordable health care has become.  Aside from the political issues, I applaud the informative information, and they make great use of subheadings throughout to break up the different sections.
