A warm-up notice is a short text or email sent a few minutes before a test call. It makes the call refer to something the person has already seen, the way a real attacker primes a target. The campaign sends the notice, waits the delay you chose, then places the call.
Any campaign that sends a notice needs the tick Messages to staff phones and inboxes are in scope for this engagement. at launch. See Authorise and launch.

​
Before you start

  • A campaign where you want the notice. It is set under Before the call on the Who calls step. See Build a campaign.
  • For email from your own domain: access to your domain’s DNS records.

​
How a warm-up notice works

The rules that apply to every notice:
  • The text may name the person and their own company. It may never name a real outside brand. A notice that names one is refused and the default template is used instead.
  • A person who replies STOP to a text, or clicks the opt-out link in an email, gets no more notices.
  • Notices are capped at 500 per workspace per day.
  • A person with no address on the chosen channel gets no notice. The report shows which notice each call had.
Every call records the notice it had, so the results page compares calls with and without one. See Read your results.

​
Who the notice comes from

Today the verified domain is not yet used as the sender: warm-up emails still come from hello@deepblocker.ai, even when your domain shows Verified.

Steps to verify your domain

Open the sender card

In the console, open Red Team, then the settings page titled Fair testing. Scroll to Warm-up email sender.

Add your domain

Under Sending domain, enter a domain you own, for example mail.yourcompany.com. The help text says: “Must be your own company domain, never a third party’s.” Under From name (optional), enter the name to show on the email, for example “Your IT team”. Click Add domain.The status shows Pending verification and two DNS records appear.

Add the two DNS records

Add both records at your domain host. Use the copy icons next to each Name and Value.If your domain already has an SPF record, add include:spf.mtasv.net to it instead of adding a second one.
4

Verify

Click Verify DNS. Each record shows found or not found. When both are found the status becomes Verified with the date. If not, the page says: “Not verified yet. DNS can take a while to spread; try again shortly.”

​

Problems

DNS changes can take up to an hour to spread. Check the record name is exact, including the deepblocker._domainkey. part, then click Verify DNS again.
The value is not a domain. Enter the domain only, without https:// or an email address in front.
Check the person has a phone number or email address on their contact for the channel you chose. Check the daily cap of 500 has not been reached. A person who replied STOP or opted out gets no notice.
Your text named a well-known outside brand, or was over 600 characters. The default template was used instead. Edit the text and keep to your own company name.
