Methodology

How we collect, compare, and update the data on this site.

What's covered

On 2026-11-12 we read the official pricing pages and help docs for 15 services. Everything on this site comes from that documentation. We have not tested the products ourselves, and we have not run deliverability or speed tests.

What each status means

Documented

The vendor's documentation describes the feature or limit.

Limit applies

The vendor describes a restriction, quota, or tier condition. Read the value and its note.

Paid add-on

The feature costs extra on top of the plan.

Not included

The vendor's documentation says this plan does not include it.

Not verified

We couldn't confirm it. This does not mean the feature is missing.

Keeping terms comparable

We never merge daily and monthly sending limits, static pages and CMS items, contacts and subscribers, or monthly and annual billing. "Unlimited" is the vendor's word, and the vendor's terms still apply. Domain renewals, taxes, usage charges, and payment processing can add cost.

Sources and dates

Each verified value links to the vendor's page and has its own permanent link on this site. "Checked" is the date we read the source, not the date the vendor changed anything. Unverified values have no check date. Rebuilding the site does not change any dates.

Corrections and changes

We review every source change before publishing it. The downloadable data has the same values as these pages. If we add our own tests, we will publish how we ran them and what we found. Prepare a correction report.

Editorial standards

Every service page has the same two sections on who the service suits and what to check, each citing vendor sources. Services in a category are compared on the same features. We describe which situations a service fits. We don't give star ratings or name an overall "best".

Every value keeps its plan, billing term, audience size, sending period, and product edition. A limit on a cheaper tier is not presented as missing from the whole product. If documentation is missing or contradictory, we mark the value "Not verified", not "Not included".

Some service pages have more detail than others, such as extra feature explanations and FAQs. A longer page is not a stronger recommendation. The plans we cover don't include every feature a product offers.

Service lists are alphabetical. We chose the featured comparisons ourselves, and they are not ranked by popularity. This site has no affiliate links. We will disclose any ownership, employment, or paid relationship with a vendor, and such a relationship will not change how we check sources or order lists.

Data formats

Every page is plain HTML with linked sources. The same data is available as JSON, CSV, and Markdown, all built from one catalog.
