Describe an email in a sentence, attach a logo or a brief, and get an editable React Email template you can publish and send.

Reads

Your description and up to four files: a logo, photos, a PDF brief or a text file.

Gives you

An ordinary template made of React Email blocks, saved as a draft you can rewrite, restyle or rearrange.

Costs you

An account, because the template is saved to your workspace. Your description and files come with you when you sign in.

A domain’s SPF, DKIM, DMARC, BIMI and MX read from live DNS, with the SPF lookup count you have left.

Reads

SPF, DKIM, DMARC, BIMI and MX from live DNS, so you see what a receiving server sees rather than what a record was meant to say.

The SPF count

SPF allows ten DNS lookups. Every include, a, mx and redirect spends one, and going over stops the record evaluating, which fails silently. The headroom is shown as a number.

Costs you

A domain name. No account, no verification email, and no report held back until you book a call.

Read a domain or an email address and see the BIMI record, the logo it points at, and why an inbox is not drawing it.

Shows you

The published record, the logo drawn as the file itself rather than a screenshot, whether a Verified Mark Certificate backs it, and the DMARC policy underneath.

The usual answer

A logo that will not appear is nearly always DMARC below p=quarantine, a missing a= authority, or an SVG the spec does not allow. Each is named rather than scored.

Costs you

A domain or an email address. The logo is fetched and stripped of scripts and remote references before it is ever drawn.

Type an email address and see whether it is written correctly, whether its domain takes mail, and whether it is a throwaway or shared mailbox.

Checks

The syntax, the mail servers of the domain, throwaway domains, shared addresses such as info@, and likely typos such as gmial.com, with a correction.

Never does

Send anything to the address or connect to its mailbox. Its owner never finds out it was checked.

Costs you

An email address. Nothing is stored.

A throwaway inbox that takes real mail for an hour, with the tracking images stripped before you read it.

Gives you

An address that works for an hour and takes real mail while it does, so a signup that wants a live inbox gets one and does not get yours.

Strips

Tracking images, before the message renders. A throwaway address is mostly used for signups, and a confirmation email is the message most likely to carry a pixel.

Keeps

Nothing. The inbox goes when the hour is up and there is no account to attach it to.

Reads the record a domain publishes today, then builds the next one with a warning on every step that drops mail.

Reads

What the domain publishes at _dmarc today, then builds the next step from it. None becomes quarantine, quarantine becomes reject.

Warns on

The five things that quietly drop mail: no rua address, a jump straight to p=reject, a pct below 100, any ruf at all, and strict adkim or aspf.

Leaves to you

Publishing it. Nextmail writes MX, SPF and DKIM for a domain it hosts and deliberately not this one, because p=reject can quarantine somebody’s invoicing overnight.

A year of per-seat mail for your team, priced against the same team per domain at every vendor’s list price.

Prices

A year of mail for your team against every vendor on the comparison page, at each one’s published list price.

Shows

The asymmetry, in the arithmetic rather than the copy: the mailboxes slope with headcount and the sending tools with volume. Ours steps with domains and sends, and a paid plan does not move when somebody joins.

Moves

Volume, on every row that prices it: Resend and Mailchimp by their tiers, the mailboxes by the seats their sending caps need, and ours by plan.

Set your own hours, add colleagues in other timezones, and see the window when everyone is working.

Reads

Your timezone and hours, and a name, timezone and hours for each colleague you add.

Shows

Each colleague's local time now, how their day overlaps yours, and the one window the whole team shares.

Keeps

Nothing. The list lives in this tab and is gone when you close it.
