FAQ
Free tools, answered
Short answers about the free tools.
Are the tools really free?
Yes. Every tool on this page is free, with no sign-up and no limit on how often you use it.
Is what I type stored anywhere?
No. The tools run in your browser. The domain email checker and the SPF lookup count ask Cloudflare's public DNS for records; nothing goes to ZicReach.
Which tool should I start with?
Run the domain email checker on the domain you send from. Fix anything it marks as failed with the SPF and DMARC generators, then check your copy with the spam word checker and subject line tester.
How do the tools relate to ZicReach?
They use the same rules as the app: the spam word list from the ZicReach editor, and the recommendation of at most 20 emails a day per mailbox and 3 mailboxes per domain. In ZicReach, warmup is free and these checks run as you work.
