Type the domain you send email from. We read its SPF and DMARC records from DNS, tell you what is missing or wrong, and suggest a record to publish when there is none. No sign-up, and nothing is sent.
SPF lists the servers allowed to send mail for your domain. A receiving server checks the sender against that list. Without it, or with a record that breaks one of the rules, your mail is more likely to land in spam.
DMARC tells receivers what to do with mail that fails SPF or DKIM: deliver it, send it to spam, or reject it. It also asks them to send you reports, so you can see who sends mail as your domain. Start with p=none, read the reports, then tighten the policy.
DKIM signs each message. Its record sits under a selector name that only your mail provider knows, so it cannot be looked up from the domain alone. Your provider's admin panel shows the selector and the record to publish.
Eveil finds your prospects, writes the emails and sends them from your own mailbox, one at a time, like a person would.
