In a world powered by search and social algorithms, it can be hard to find authentic content these days. That's why this website exists — to surface the best marketing content available. So, here's a roundup of the best email marketing blogs previously featured on Marketer Milk.
Email marketing campaigns are still the lifeblood of many businesses, particularly those offering B2B products and services. Although sales success occurs in relatively low proportion (around 1.22% of sales emails result in a conversion) it remains a very inexpensive strategy, with an average ROI of $42 for every dollar spent. As you scale up, this ROI makes the enterprise worthwhile, and digital marketing automation makes it very possible.
There are plenty of blogs offering advice on how to optimize campaigns, enhance your email marketing efforts, and give reviews on the latest email marketing automation platforms and tools. With such variety on offer, how do you know who to trust?
We’ve collated some of the most useful and interesting email marketing blogs, and summarized what’s on offer in each one in the following article.
First let’s decide what makes a useful email marketing blog, so that we have criteria with which to judge the candidate sites.

What to look for in email marketing blogs
Here’s what we believe makes for a good blog:
- Readability: Clear, concise, and snappy content with no filler.
- Regular updates: New posts are made every few days.
- Authority: Coming from a source with first-hand knowledge.
- Data-led: Information is derived from facts and data, rather than opinion.
- Insight: Real lessons can be learned from the content.
- Variety: The blog doesn’t feature the same content recycled endlessly.
- Objectivity: The content isn’t focused on making you purchase the site’s product.
- Image-led: How to articles are illustrated with screenshots and examples.
While there are other features that make a blog worth reading, we believe these eight qualities make for a perfectly composed blog article. Now let’s look at the contenders.

Okay, let's look at what each blog has to offer.
1. Litmus Blog
Litmus is an all-in-one email marketing service, and clearly their blog is part of their strategy to obtain new clients. However, their blog does contain a wide range of compact, incisive email marketing tips, and they publish several per week. Recently Litmus has published discursive pieces on such topics as email personalization, design and marketing trends, and recent technological changes such as Gmail pre-fetching images, which can affect your email open metrics.
Litmus’s articles are well-written, categorized by topic for easy searching and an indication is given of how long they’ll take to read. The data quoted therein is well-referenced with links to sources. Where pieces directly discuss Litmus products and partners, this is made clear.

2. Iterable’s Blog
Omnichannel marketing platform Iterable hosts a blog posting new articles every five to seven days. Their subjects are more varied than email campaigns alone, and they tend to be very current. There’s an article on “trendjacking,” for instance, which references the stellar recent success of Wordle over the last few weeks.
Iterable’s articles are largely written by in-house authors but there also guest writers who inject a lot of personality and opinion into their pieces, making them a fun read. Their articles also tend to be more in-depth and longer than many competing blogs. They are also helpfully sorted into topics — Company, Product, Engineering, Customer Experience et cetera.
This is a great blog to read if email marketing is just oner small strand of your omnichannel marketing strategy.

3. SendGrid Email Deliverability Blog
SendGrid, an email automation product from Twilio, have their own branded blog called “The Full Send.” Like Litmus, their pieces tend to be short, taking around 3-8 minutes to read. They are notably more focused on email marketing matters than some more wide-ranging blogs.
Crafted by named writers, there are some laser-targeted and unusual topics such as the use of emojis in email campaigns and how to write an invoice email. Some of the articles are linked to specific SendGrid templates. There’s a strong focus overall on how to construct good emails for specific marketing purposes, which could be very useful for junior staff members learning the ropes.

4. EmailOctopus Blog
Email platform Octopus, whose clients include entertainment industry brands and not for profit providers, have a blog very much targeted at those composing emails for specific purposes. These include the construction of customer surveys, mailing list expansion and lead capture. There are also up to the minute pieces on developments within the industry, including, as exemplified below, the Google Ads grant for nonprofits.
Articles are in-depth, practical, and well-illustrated with a step-by-step approach to creativity. Authors are named and references are properly linked, making this a very professional blog, which publishes new content roughly every 3-6 days.

5. Klayvio Blog
Klayvio, a popular ecommerce email marketing software, goes big and bold in its blog, with large, colorful illustrations and dramatic headlines. Here’s an example: “Sex, Drugs and DTC: Why ‘Taboo’ Brands are Owning Marketing.”
Their articles are categorised under seven headings including “Email Marketing”, “SMS Marketing” and “Acquisition.” Articles are in-depth without being overwhelming, and there are highlighted quotes from industry leaders to drive key points home.
Their “how to” articles include a good range of brand examples, and the interview-style features are a great addition. Kayvio manages a good balance between informative and entertaining, with a sober yet readable style.
6. GetResponse Blog
GetResponse post almost daily on topics as diverse as landing page design and chatbots, so it’s not a blog completely focused upon email marketing best practices. Their articles are usually tagged, rather than posted under a single category, so readers can cross-reference and find other similar posts, a helpful feature.
They use a lot of screenshots, breaking up articles which can run to 2500-3000 words. In keeping with the level of detail on offer, the style can be a little academic at times, but it’s never less than useful. When the occasion demands, such as their Valentine’s Day piece, their writers adopt a much more casual and fun approach.
Examples and screenshots enliven their “how to” features and pieces which emphasize new GetResponse products or features are clearly labelled.

7. ActiveCampaign Blog
This leading CRM automation platform posts under several strands, which are sequentially listed on their landing page, although you have to scroll down to reveal each topic. Headers include Growth, Updates, Culture and Spotlight.
Culture is particularly unusual, delving into such topics as Black Lives Matter, businesses surviving the pandemic and combating poor mental health. The eclecticism of the blog definitely makes it stands out from more procedural contenders.
Spotlight explores some case studies, and the Growth strand delves deeper into content marketing and CRM issues. This is a good blog to follow if you want to read around the customer relationship topic in general, rather than just focus on email campaign issues.
A small criticism might be that it’s a little clumsy in terms of navigation. Posting dates are not very specific but it appears they post several new articles weekly and authorial styles vary from the casual to the semi-formal.

8. AWeber Blog
AWeber is a landing page builder which helps optimize email engagement and mailing list subscriptions. Their blog articles are often accompanied with attractive, punchy infographics rather than stock photos.
The sales function is foregrounded. Case studies of satisfied clients intermingle with more newsworthy or “how to” type pieces. For instance, there’s an article by a work from home mom and entrepreneur who uses the platform. The practical articles are well-illustrated with plenty of data, as well as bullet-points to highlight memorable tidbits.
Read length is about 3-8 minutes per article, with recent pieces covering such topics as subscription gathering and SEO optimization.

9. Mailchimp’s Blog
Mailchimp probably needs no introduction, being one of the world’s leading email marketing and newsletter platforms, named in 2021 as one of G2’s Best Global Software Companies.
Its blog is well-designed with illustrations accompanying each article and an ornate font for its headers which somewhat resembles the New Yorker’s iconic typeface. Mailchimp’s “how to” articles are lengthy and erudite, and written in a semi-formal manner.
There are customer case studies to help inject more personality into Mailchimp’s content. Uniquely, some of these are accompanied by interview clips, which add variety. Illustrations in a hand-drawn style inject a down to earth tone. There are occasional, marketing book round-ups too.
Small quibbles — it’s not easy to filter all articles in one strand or see posting dates until you click on an individual article. Otherwise, this is a predictably excellent blog.

10. The Email Marketers Blog
Specialist email marketing agency The Email Marketers certainly know their topic, being a globally distributed team of experts. There are articles on the basics (A/B testing, market segmentation), deep dives (retention emails, holiday email marketing), email marketing tools, and features on some of their clients and partners (including Klayvio), as well as occasional press releases.
Thematically related articles are highlighted alongside the piece you’re reading, a nicely intuitive feature. Although their in-depth pieces might lack backlinks and references, they aren’t short on insight, such as the example piece below.
- Sample article: Top Ten KPI for Email Marketing
11. Keap’s Email Marketing Blog
Keap’s email marketing articles are a strand within their overall B2B marketing blog, and as such are posted roughly monthly. Nevertheless, they are worth reading, and referencing, since they contain a lot of fascinating data and insight.
For instance, the example article given below reveals that over 47% of subscribers open emails, inspired by the subject header alone. Their editorial style is accessible and easy to read, and the headers of thematically linked articles are interspersed, leading you down new, fascinating rabbit holes.
Keap is an all-in-one CRM, and the various strands of its two blogs (marketing and product) are well worth a visit too.

12. SendX Blog
Helpfully tagged for subject matter, SendX’s articles take between 5 and 10 minutes to read and cover topics as wide-ranging as how to increase attendance at online events/webinars and the marketing of crypto products.
Unusually for marketing blogs, you can filter by article author as well as topic or tag, making this one of the easiest blogs to navigate. Colorful illustrations and screenshots break up the text and authorial style ranges from collegiate to semi-formal. Another useful feature are the embedded tables of contents, so you can jump straight to a salient point.
Our only real quibble for this far-reaching blog is that articles aren’t dated, and it’s not easy to see how frequently the blog is updated.
13. Campaign Monitor Blog
A unique feature of Campaign Monitor’s blog is that it tells you which articles are trending, so you can check out what’s especially popular before delving deeper. Subjects are cleverly specific and current, such as their piece on the difference between marketing to Gen Z and Millennials. You'll find many different topics ranging from email marketing strategy to social media.
There are explanatory graphics (some of the best we’ve seen) and links to helpful resources, making this a great resource to share. Campaign Monitor’s email builder is strong on eye-catching design and their blog follows suit with a grid-format image-led layout and short summaries which appear when you rollover each header.
Articles take up to ten minutes to read and are posted several times per month, though not to a regular schedule. It’s a very well-composed and attractively designed blog.

14. The Moosend Marketing Blog
Email service provider (ESP) Moosend has a unique filtering system for its blog — you can selectively reveal articles aimed at beginner, intermediate or advanced marketers. There are also sidebars highlighting resources and tutorials in case any of the subjects inspire a need to know more.
Articles are listed on a scrolling page with subjects, authors and opening paragraphs highlighted. Read More buttons are provided to take viewers to the article in question. There are also carousels of highlighted features.
Moosend’s articles are thorough, well-referenced and the text is broken up with bullet points and screenshots to illustrate key learnings. Listicles provide a lot of links to useful tools and authors are named. Most helpfully, a lot of great examples from top brands are used throughout their “how to” entries.

15. Designmodo Blog
Designmodo goes bold on its blog page with giant illustrations and large headers. As you might expect from a design-led platform for email templates and landing pages, there’s a focus on design. Recent topics include current web design and UI trends, Valentine’s Day email newsletters and email marketing campaign structure.
New posts appear roughly weekly, and a table of contents is provided, as well as plentiful illustrations and screenshots. Bylines are given, allowing readers to build a relationship with bloggers they trust. Visitors can click on a writer’s name to reveal a little more about their experience and expertise, as well as all the articles by that individual.
News articles are easily located from the blog page and there are “Editors’ Picks” to facilitate browsing. It’s another great blog to add to your browser favorites.
