Four free tools for cold email, no signup

Four small tools are now live at talyro.app/tools, free and with nothing stored. Each one runs on real logic already used inside the product, not a simplified stand-in.

The SPF, DKIM & DMARC checker (already live, now extended) looks up a domain's real DNS records and reports what's missing. It now also checks whether the domain's mail server IP is listed on Spamhaus, SpamCop, or Barracuda's blacklists.

The email verifier checks whether a single address is real and safe to send to, using the same ZeroBounce integration Talyro runs automatically before spending a credit on a lead. Worth knowing: some providers (Zoho among them) deliberately block verification probes even for real, working mailboxes, as protection against address harvesting — so an occasional false 'invalid' is possible. A real send is the only way to know for certain.

The cold email opener generator takes a one-sentence description of who you're targeting and what you're offering, and writes back three different opening lines — the same AI that drafts Talyro's own first-touch emails, without the lead-finding behind it.

The sending volume calculator shows the safe daily send cap for a mailbox on warmup, using Talyro's actual warmup ramp rather than generic advice — enter when a mailbox started sending and its eventual daily limit, and it shows today's cap and how that climbs over the following weeks.
