Tools we built because we needed them.
No sign-up, no email wall, no credit card. Every one of these runs in your browser, so nothing you paste is uploaded anywhere, including to us.
Missed Call Calculator
Four numbers you already know turn into the figure you have been avoiding: what unanswered calls cost you every month and every year.
Spam Checker
Paste an email and see the words that send it to the junk folder, split into what genuinely matters and what is fine in normal writing.
Email Reputation
Live DNS lookups on the records that decide whether your mail is trusted. Most small businesses are missing at least one of them.
SMS Compliance Checker
Texting carries more legal exposure than any other channel a small business touches. Check a campaign before it goes to a list.
SMS Segment Calculator
Texts bill by segment, not by message. One curly apostrophe can halve your character limit and quietly double the bill.
Why give these away?
Because the paid versions of these tools mostly exist to collect your email, and half of them inflate the problem to make the upsell land. We built ours to give a straight answer. If they save you a job you'd have lost, you'll have a fair idea whether the rest of what we make is worth a look.
The tools find the problem. Sales Nest fixes it.
Email, texting, missed-call text back, and a calendar that fills itself. One flat price, every feature included.
