Frequently asked questions

What does Email template do?

Build a simple HTML email with a live preview.

When would I actually use this?

Reading a send properly: what the open and click rates mean once bounces are removed, how fast the list is decaying, and what volume a target reply count needs.

What is the most common mistake?

Treating the open rate as a measure of interest. Image-blocking and privacy proxies open messages nobody read, and inflate the figure by a margin that varies with the audience's mail client.

How is Email template different from Email list growth rate calculator?

They sit next to each other but answer different questions: Email list growth rate calculator is the one to open when you need it to compute the net growth rate of your email list from new subscribers and unsubscribes. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Email marketing ROI calculator is the closest one after this: Walk a campaign from emails sent through delivery, opens, clicks and orders to revenue, then to margin, ROI and ROAS. Each rate stacks on the previous step, so you see exactly where the funnel leaks — plus revenue per email, cost per order and the break-even conversion rate.

What else is worth having open alongside it?

Email open rate calculator and Email signature — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

The rates are computed from the figures you supply. Whether your platform divides by sends or by deliveries changes every percentage, so compare within one tool rather than across two.

ExplainerEmail Open Rate Is Broken. Measure Click-to-Open InsteadApple Mail Privacy Protection pre-fetches tracking pixels, so a share of your opens were never opened by a person. Open rate now moves with your audience's mail client. Here is what survives, worked on a single send.ExplainerWhat an Email Programme Actually ReturnsThe famous email ROI multiples are self-reported survey figures with the labour left out of the denominator and revenue that would have arrived anyway left in the numerator. Build the honest version instead: incremental revenue against full cost, measured with a holdout — and the arithmetic of how big that holdout has to be.ExplainerOpen Rate Is a Measurement of Your Audience's Mail ClientThe denominator should be delivered, not sent — which means defining hard and soft bounces properly. Unique and total opens are different numbers. And a reported open rate has a computable null point: past a certain share of prefetching clients it carries no information about humans at all. The instrumentation that replaces it.GuideEngagement Rate Formulas by Platform: Why the Same Post Scores 2% and 4.8%Engagement rate is not one metric. Divide by followers, by reach or by impressions and the same post returns three different numbers — and every platform defaults to a different denominator.ExplainerGrowing an Email List Is a Leaky BucketConstant additions against a proportional loss rate do not grow forever — they converge on a ceiling equal to additions divided by the loss rate. Here is that ceiling computed for six loss rates, why a list can grow while its engaged half shrinks, and the feedback loop that makes a bought list self-defeating.How-toHow to Calculate NPS: The Formula, a Worked Score, and What It HidesPercentage of promoters minus percentage of detractors. Passives sit in the denominator and nowhere else, the result runs from −100 to +100, and it is not a percentage despite looking like one.
