Cost Of Email Bounces: The Verified vs. Unverified List Cost Gap

Cost Of Email Bounces

Most articles about the cost of email bounces open with a hypothetical. Say you send 100,000 emails. Say your bounce rate runs at 4%. Say your average order value is $75.

Google & Yahoo Bulk Sender Requirements: What’s Identical, What Isn’t & What’s Coming Next

Google & Yahoo Bulk Sender Requirements

Cross Google’s 5,000-email-a-day threshold once, even by accident, and you become a bulk sender. Permanently.

Ecommerce Email Marketing

Automated flows make up about 2% of the emails an ecommerce store sends. Omnisend’s own 2026 data puts their share of total email revenue at 37%.

The Email A/B Testing Guide: What to Test First, What Corrupts Your Results, and How to Build a Programme That Keeps Improving

Email A/B Testing

A/B testing in email marketing is the closest thing we have to a controlled experiment in a channel built on variables. You isolate one element, run it against a control, and let your audience’s behaviour tell you what works. In theory, every test advances your programme. In practice, most email A/B testing produces far less … Read more

Why Buying Email Lists Is a Bad Idea: What It Does to Your Domain, Your Sender Reputation & Every Campaign You Send After

Why Buying Email Lists Is A Bad Idea

The pitch is always the same. You need contacts. You need them quickly.

For businesses under pressure to scale their email marketing, understanding why buying … Read more

What Is Email Segmentation: 6 Types, Proven Strategies & Real Examples That Drive Results

Email Segmentation

If you are sending the same email to every person on your list, you are not running an email marketing programme. You are running a broadcast.

Email Marketing Guide

If you search for an email marketing guide today, you will find dozens of them. Most follow the same template: a definition, a list of email types, a few tips on subject lines, and a CTA to sign up for whatever ESP is sponsoring the post. They are not wrong, exactly.
