Channel-by-channel requirements

How consent, setup, and screening expectations differ across email, SMS, calling, direct mail, and ringless voicemail.

Updated 2 min readMaintained by Landing Zone

Every outreach channel carries its own consent, setup, and screening posture. Channel rules do not transfer: permission to email someone is not permission to text them, and a number you may call manually is not automatically fair game for automated messaging. Review the dedicated page for each channel before you use it.

Email

  • Commercial email generally rests on truth and transparency: a truthful sender identity, accurate subject lines, and a physical mailing address in your messages.
  • A functioning unsubscribe, honored promptly, is a baseline expectation. Landing Zone adds one-click unsubscribe to campaign email and tracks opt-outs.
  • Ongoing hygiene matters: rising complaints and bounces hurt deliverability and usually signal an audience problem.

SMS

  • SMS generally carries stricter consent, carrier, and registration considerations than ordinary commercial email. Do not carry email assumptions into texting.
  • Landing Zone requires VERIFIED consent before a contact is eligible for batch or campaign SMS; imported and skip-traced contacts start UNVERIFIED.
  • Carrier registration (A2P 10DLC) applies before you send business SMS at scale, and SMS sending gates on approved registration status.
  • Screening layers apply automatically: the suppression list, quiet hours, and the 30-day repeat-contact cooldown.
  • Full details: SMS consent and Cold SMS risk.

Calling

  • Consent expectations generally differ between autodialed or prerecorded calls and live calls a person dials one at a time. Landing Zone supports only human-initiated click-to-call — there is no predictive or auto-dialing.
  • Numbers are screened against your workspace suppression list, imported DNC data, and known-litigator entries before a call connects.
  • Quiet hours are enforced for calls as well as SMS.
  • Full details: Calling considerations.

Direct mail

  • Postal outreach has a different posture from phone channels: no carrier registration or texting-style consent mechanics, but truthfulness rules and state-level requirements for certain activities still apply.
  • Direct mail is in development in Landing Zone. There is no sending capability today, so no sending steps are documented.
  • Full details: Direct mail considerations.

Ringless voicemail

  • Ringless voicemail is coming soon to Landing Zone. No capability exists today.
  • It delivers a recorded message to a voicemail box. Do not assume that skipping the ring avoids calling-style consent expectations — plan for a conservative, consent-first posture.
  • Full details: Ringless voicemail considerations.

Your responsibilities across every channel

Whatever the channel, you own the audience, the consent, the content, and the timing. Landing Zone's controls are uniform product defaults, not channel-specific legal determinations.
