Tue, 13 Jan 2026 11:08:56 +0000

Good Friction

Fri, 05 Dec 2025 07:10:00 +0000

Segmentation and personalization – the path to increasing recipient engagement

Thu, 06 Nov 2025 09:15:00 +0000

Segmentation and personalization of emails are proven methods for increasing the relevance of email marketing for your recipients, but the way they work is different. Together, they lead to increased recipient engagement, which is a positive signal for email service providers (ESPs) and can therefore support increased deliverability in the long term.

How to Choose the Right Emailing Platform

Thu, 02 Oct 2025 10:11:00 +0000

Are you at the beginning of your journey and choosing your first email marketing platform? Or are you already using a sending platform, but it's time for a change? Whether you're a complete novice or an experienced marketer, choosing the right tool is no trivial decision. It's an investment that can fundamentally affect not only the effectiveness of your campaigns, but also your overall marketing performance.

Have You Changed Your Tool? New Beginnings Await

Thu, 02 Oct 2025 09:38:00 +0000

Switching Email Service Providers may seem like a small change, one that no one will notice. For your recipients, that really should be the case (just make sure to upload all bounced and unsubscribed addresses into the new platform before sending). But behind the scenes—both technically and reputationally—this change matters a great deal. The old saying applies here: measure twice, cut once – and maybe even measure three times. Precision and care are important, because mistakes can have a long-lasting impact.

Mailkit’s Guide to Schemas – Part 1

Fri, 28 Feb 2025 15:00:00 +0000

As email marketers, we are always trying to engage our audiences and improve their email marketing experience. A more engaged audience means better deliverability and inbox placement, and ultimately a better return on investment. One of the best ways to accomplish this is by setting up authentication on your own custom, clearly branded domains, and sending relevant and timely content to your audience.

Who is unengaged?

Fri, 08 Mar 2024 07:50:00 +0000

The question of what to do with inactive or unengaged recipients comes up fairly frequently at every conference and workshop we attend or client events we hold. The answers vary a lot depending who’s speaking, what business they are in, etc. There is one major divide - the marketeers vs the deliverability people.

Affiliate marketing is a very popular marketing method in the e-commerce space. It can be extremely efficient as an acquisition channel. It does however come with significant risks that need to be mitigated - preferably by the brand’s terms for affiliate partners.

Reactivating your unengaged (or not)

Let's start off by saying there is a lot of disagreement surrounding this topic. Not just between marketers and compliance and deliverability people but even within deliverability circles.

Is email dying?

Tue, 31 Oct 2023 07:39:00 +0000

If you were following the tech industry news in the past 2 decades you have surely come across articles that pop-every January announcing the Death of email. So it’s settled - email is dead - why else would this be a recurring topic every year? But there is a contradiction right there - the death of email has been announced by many writers for 2 decades and now, at the end of 2023 I’m writing an article about this very topic.

Should you worry about opens and clicks?

Tue, 25 Apr 2023 11:05:00 +0000

Marketers often rely on open-and-click rates for quick campaign performance evaluations. Yet these metrics have long been known to be inaccurate. We often believe that things on the internet improve over time. That is not the case with email metrics - they are getting less accurate. Why? Should you be worried, and should we abandon these metrics altogether?

Beware the lists

Mon, 14 Nov 2022 13:23:00 +0000

We’ve all been there - there is a listing on a blocklist and the panic kicks in… and then nothing really happens. Not all blocklist are equal and considering there are hundreds of them it should not be surprising. Some blocklists are simply more important and some might be more relevant to your particular target group. Whatever your point of view one thing is certain - blocklisting is a signal of something significant no matter what the impact. Most likely you also use some service to monitor these blocklists (which is definitely not good for your mental health) but what if I told you there are a whole lot of listings you are missing? Agreed - this is also not good for your mental health but better now then never...
