A better send
starts here.

Type a domain, get its SPF record with every mechanism explained, the DNS-lookup count against the limit of 10, and what to fix.

DMARC tells inboxes what to do with mail that fails authentication.

Check the signature that helps prove your email is really from you.

Check whether a domain is set up to receive email.

Checks a sending domain or IP against the public DNS blacklists that allow browser lookups.

Syntax, the domain's mail server, disposable domains and role accounts, checked in your browser.

Tick the providers that send mail for the domain, add any extra IPs, copy the record into a TXT entry at your DNS host.

Answer two questions, copy one record.

Rule one of infrastructure: your primary domain never sends cold email.

Build a clean signature that keeps the focus on your message.

Name plus domain in, every common corporate email pattern out.

Three numbers in, your campaign judged against the benchmark that matters: interested replies per contact reached.

Two numbers in, one verdict out: your bounce rate against the thresholds that decide whether your next send lands.

The infrastructure math behind any serious campaign: contacts to touches to sends per day to inboxes to domains.

New inboxes earn trust slowly.

Get a second opinion on your draft before it lands in someone’s inbox.

Spot words that could make your email sound like a sales blast.

Type a subject line, see how it survives a phone screen, a spam filter and a skeptical human.

Paste spintax like {Hi|Hey|Hello} {{firstName}}, count real variants, preview samples, and catch broken braces before launch.

The first thing your prospect sees is not your email.
