Weighs your volume, budget, data needs, and team shape against every platform in our catalogue, and shows the reasoning behind the match.
Open toolSpam Word Checker
Paste your cold email, see what trips spam filters.
Flags trigger words, link patterns, fake Re: subject lines and unfilled merge tags before you send. Runs entirely in the browser — nothing is uploaded.
Open toolSPF / DKIM / DMARC Checker
Audit the DNS records that decide whether you land in inbox or spam.
Enter a sending domain and see its SPF, DKIM, DMARC and MX records, with what each result means — including the misconfigurations that are worse than having no record at all.
Open toolMailbox Volume Planner
Work out how many mailboxes and domains your send volume needs.
Turns a daily send target into the mailbox count, sending domains and warmup ramp required — with the arithmetic shown and every assumption editable.
Open toolEmail Permutator
A name and a company domain into every likely address format.
Generates the seventeen or so formats a work address usually takes, grouped by how common each is. Candidates to verify, not answers — the page is explicit about that.
