About this blog
Written from real support conversations, not a content calendar.
The K2Mailer blog exists to answer the questions that come up while you are actually running email campaigns, not while you are reading a textbook about email marketing. Most of what gets written here starts as a support conversation, a pattern we noticed across customer accounts, or a question that kept coming up in onboarding calls. That is why the guides tend to be specific. Instead of a generic post on subject lines, you will find articles that walk through why a sender reputation dropped, how suppression rules interact with double opt in, or what actually happens when a segment and a list target the same schedule.
Email marketing is a strange discipline because the fundamentals barely change, but the mechanics underneath them keep shifting. Inbox providers update filtering models, authentication requirements tighten, and audience expectations move as more of their day gets pulled into other channels. The blog tracks all three of those layers. Strategy posts cover planning, offers, and testing. Deliverability posts cover authentication, list hygiene, bounce handling, and complaint management, since a beautifully designed campaign is worthless if it lands in spam. Automation posts cover the drips, triggers, and re-engagement flows that keep a list warm between big sends. PushWave posts cover the web push side of the same problem, since a browser notification and an email share the same underlying question of permission, timing, and relevance.
Whether you should use this blog or the help center depends on what you already know. The help center documents how a specific K2Mailer feature works, screen by screen, with the exact steps you would follow inside the app. The blog is where the reasoning lives. If you already know you need to build a segment and just want the steps, the help center is faster. If you are trying to decide whether a segment or a list is the right audience type for a re-engagement campaign, or why your open rate dropped after a list import, the blog is where that judgment call gets explained.
Common questions
Before you dig into the guides
- How often is new content added to the blog?
- New guides go up as real questions surface across support tickets, onboarding calls, and product changes. There is no fixed publishing schedule, because a rushed post written to hit a calendar date is usually a worse use of your time than a slower one that actually resolves the question. When K2Mailer ships a feature that changes how audiences, deliverability, or automation work, the related guide gets updated rather than left to go stale.
- Do these guides apply to PushWave as well as email?
- Some do and some do not. PushWave is a separate product from K2Mailer email, but they share the same underlying discipline of permission based communication, so strategy concepts like segmentation, timing, and re-engagement carry over between the two. Posts tagged with the PushWave category are specific to web push notifications, while posts tagged K2Mailer are specific to email. Where a concept genuinely applies to both, the guide says so directly instead of leaving you to guess.
- Is this blog written for beginners or experienced senders?
- Both, depending on the post. Getting started guides assume no prior email marketing background and explain terms as they come up. Deliverability and automation guides assume you already know the basics and go deeper into edge cases, like what happens when a hard bounce interacts with a suppression list, or how a trigger behaves when a contact belongs to more than one list. Each article states its intended audience near the top so you can judge fit quickly.
- How does the blog relate to the K2Mailer help center?
- The help center is reference material. It documents each screen, setting, and workflow inside K2Mailer so you can complete a specific task correctly. The blog sits one level up. It explains why a workflow is built the way it is, when to choose one approach over another, and what tends to go wrong when senders skip a step. Many blog posts link directly to the relevant help center article for the exact click by click instructions.
- Can I suggest a topic for a future guide?
- Yes. If a question keeps coming up in your own campaigns, there is a good chance other senders are running into the same thing. Reach out through the contact page with what you are trying to figure out, and if it is a pattern worth documenting, it becomes a candidate for a future post rather than a one off support reply that only you get to see.
