This article will walk you through preparing your website, registering in Lofty, campaign setup, and common error codes.

Phase 1: Prepare Your Website (Do This Before Registering)

Reviewers at The Campaign Registry will check your website against your registration. Get this right first — fixing it after a rejection means paying to resubmit.

1A. Website Basics

1B. Consent Checkboxes

All SMS consent checkboxes must be:

• Unchecked by default
• Optional (not required to submit the form)
• Allow users to submit without checking them

Use the exact wording below — your campaign's opt-in description will quote it verbatim:

Sole Proprietor

• Checkbox 1 (optional): "By checking this box, I agree to receive text messages from [agentName] regarding real estate services, property inquiries, scheduling, and related communications. Message frequency varies. Message and data rates may apply. Reply HELP for help or STOP to opt out."
• Checkbox 2: "By checking this box, I agree to the Terms of Service and Privacy Policy of this website."

Standard Brand (Marketing)

• Checkbox 1 (optional): "By checking this box, I agree to receive recurring marketing communication from [CompanyName], including auto-dialed calls, texts, and artificial/prerecorded voice messages (message frequency varies; data rates may apply; reply 'STOP' to opt-out of texts or 'HELP' for assistance); Consent not required to make a purchase. I understand that I can call XXX-XXX-XXXX to obtain direct assistance."
• Checkbox 2: "By checking this box, I agree to the Terms of Service and Privacy Policy of this website."

Note: Finalize this wording before moving on — you'll paste it directly into the registration form.

1C. Privacy Policy & Terms of Service

Your site needs both, with working links. Each must include specific SMS language:

• Privacy Policy — Add a dedicated "SMS / Text Messaging" section with:
  • A statement that users can opt out by replying STOP to any text (must be SMS-specific, not a general opt-out clause)
  • "Text messaging originator opt-in data and consent will not be shared with any third parties."
• Terms of Service — Add the following:
  • "Carriers are not liable for delayed or undelivered messages."
  • Instructions for STOP (opt out) and HELP (assistance)
  • "Message and data rates may apply."

Phase 2: Register Your Brand in Lofty

Navigate to Personal Settings → Communication → Call & Text → 10DLC Compliance and click Register Now.

Step 1: Select whether you have a Tax ID (EIN/CBN).

• Yes → Standard Brand
• No → Sole Proprietor Brand

Note: Selecting the wrong type will almost certainly fail — you'll pay again to resubmit.

Step 2: Fill in your business information. All information must be real, verifiable, and match public records.

Phase 3: Configure Your Campaign

3A. Opt-In Description

This must accurately reflect your actual website flow. Reviewers will verify it. Paste your checkbox wording verbatim — do not paraphrase.

One-step form (all fields on one page):

"Consumers opt in by completing the contact form at {WEBSITE_URL}. The form displays a checkbox stating: '[EXACT CHECKBOX TEXT]'. Checking this box is optional. Phone number is optional. All checkboxes are unchecked by default and are not required. Message frequency varies. Message & data rates may apply. Reply STOP to opt out and HELP for help."

Two-step form (email first, then full form):

"Consumers opt in by completing the two-step contact form at {WEBSITE_URL}. On the first step, they enter their email address and click Continue. The second step displays their full contact details along with a checkbox stating: '[EXACT CHECKBOX TEXT]'. Checking this box is optional. Phone number is optional. All checkboxes are unchecked by default. Message frequency varies. Message & data rates may apply. Reply STOP to opt out and HELP for help."

3B. Campaign Description

3C. Sample Messages

Provide 2–5 samples. Each should:

• Identify the sender by brand/agent name
• Use [square brackets] for variable content like [First Name] or [City]
• Include an opt-out instruction in at least one message

Note: The platform automatically appends a system opt-out message to every text. Do not include that in your samples.

Standard Brand examples:

• "Hi [First Name], new listing alert in [City]! A [X]-bed home just hit the market at $[Price]. Want to schedule a showing? — [Agent] with [COMPANY_NAME]. Reply with 'unsubscribe' to opt-out of future text communication. This message is sent from [COMPANY_NAME]."
• "Hi [First Name], a home matching your search just dropped $[X]K in price this week. Interested in taking a look? — [Agent] with [COMPANY_NAME]. Reply with 'unsubscribe' to opt-out of future text communication. This message is sent from [COMPANY_NAME]."

Sole Proprietor examples:

• "Hi [First Name], this is [Agent Name]. I saw you were looking at properties in the area — do you have a few minutes to chat? Reply with 'unsubscribe' to opt-out of future text communication. This message is sent from [Agent Name]."
• "Hi [First Name], just following up on the property you inquired about. Are you still interested? Happy to answer any questions. — [Agent Name]. Reply with 'unsubscribe' to opt-out of future text communication. This message is sent from [Agent Name]."

3D. Pre-Submission Consistency Check

Rejections most often happen because of mismatches. Before submitting, verify:

Pricing & Payment

Payment goes directly to The Campaign Registry — not to Lofty. All fees are non-refundable, including if the registration fails.

Monthly fees are charged on the 1st. The first charge is the month after your campaign is verified.
