A/B Testing With a Small List: What to Do When You Don't Have the Volume for Significance

Email Deliverability Basics: What SPF, DKIM, and DMARC Actually Do

GDPR and CAN-SPAM Basics Before You Send Your First Campaign

How Often Should You Actually Email Your List? A Genuinely Debated Question

Marketing Budget Allocation for Small Businesses: A Realistic Starting Split

Most budget allocation advice is written for a company that already has a proven channel and a sales team to match. Here's a starting split for a business that doesn't have either yet, and the mistake that wastes the most money early on.

White Space in Email Design: Why More Empty Space Usually Converts Better

Cramming more into an email feels like getting more value out of the send. The data points the other way: whitespace measurably improves comprehension, and one well-known case study saw a 232% conversion lift from removing clutter around a single CTA.

How to Write Like a Person, Not a Brand

A study that fed people two versions of the same memo, one plain, one full of corporate-speak, found the jargon version tanked comprehension and recall. Here's why that matters for email, and what an actually useful voice guide looks like.

Writing for Skimmers: How People Actually Read Your Email

Is There Really a Best Time to Send an Email? The Studies Don't Agree

"Learn More" isn't wrong, it's just doing zero work. A single pronoun swap produced a 90% clickthrough lift in one of the most cited button-copy tests ever run. Here's the mechanism behind it, and what else actually moves the number.

Email Segmentation for a Small List: The 3 or 4 Segments That Actually Move Revenue

Most segmentation advice is written for a list of 500,000 with a data team behind it. For a small list, the entire benefit comes from three or four honest splits done well, not fifteen clever ones you'll never keep updated.

Cart Abandonment Emails: Why Most Underperform, and What Actually Fixes It

The average abandoned-cart flow still only recovers a fraction of lost sales, and it's usually not the tactic that's broken. It's the timing, the discount you led with, or measuring against shoppers who were never going to buy in the first place.

Re-Engagement Campaigns: When to Send One, and When to Just Prune the List

Every list-hygiene guide says to win back inactive subscribers before deleting them. That's true for some of them and a waste of a spam complaint for others, and the difference comes down to separating "gone quiet" from "never engaged at all."
