What is Two-Way Communication?
Two-way communication is a real back-and-forth conversation between you and a lead. It starts when the lead replies to one of your texts, which signals to mobile carriers that they've engaged with you voluntarily.
Maintaining two-way communication protects your phone number's reputation with carriers. Carriers actively filter one-sided texting patterns as suspected spam, which can cause your messages to be flagged or blocked across your entire account.
The Two Rules You Need to Know
Rule 1: Your first text to a lead must include identification and opt-out language
Every first outreach to a lead must include:
Your name (first and last)
Your company
Opt-out language telling the lead how to stop receiving texts (for example, "reply end" or "reply STOP" — both work)
Rule 2: Once the lead has replied AND opt-out language has been sent within the last 30 days, you can text normally
After a lead replies to you, you're in two-way communication and can respond conversationally without re-identifying yourself on every message — as long as opt-out language has been sent to that lead within the last 30 days.
If it's been more than 30 days since opt-out language was last sent, the next text must include it again, even if you're still actively messaging back and forth.
Good News: BoomTown Automates Most of This for You
BoomTown automatically appends opt-out language to:
Your first text to a new lead, and
Every 30 days of continuing texting with that lead
This applies to both manual texts and Smart-Drip text steps — BoomTown handles compliance timing for both.
This means you generally don't need to think about opt-out timing — the system handles it. What you do need to handle is the identification portion of your first text (your name and company), since that's content only you can write.
Here's an example of what BoomTown auto-inserts. The bracketed portion is the automated opt-out text:
Hi Joe, this is Ben Testin with the Cobblestone Group. I was just reaching out to see how your home search was going?
[This part of the message is required by your mobile carrier and is sent automatically. If you prefer not to receive text messages from me just reply end]
The user wrote everything before the bracketed section. BoomTown appended the bracketed portion.
When Two-Way Communication Breaks
Two-way communication isn't permanent. If a lead stops responding, two-way communication is broken. Your next text to that lead must be treated like a fresh first outreach.
The one scenario where you must include opt-out language manually
In almost every texting scenario, BoomTown handles opt-out insertion automatically. The one exception is when:
You've previously been in two-way communication with a lead,
The lead has now stopped responding, and
You're sending them back-to-back follow-up texts without waiting for a reply.
In that specific situation, BoomTown's automatic 30-day clock will not trigger re-insertion on your next text (because the clock resets based on when opt-out was last sent, not on whether the lead has stopped responding). You'll need to manually include opt-out language on the next message yourself.
Example — manual opt-out needed:
Hi Johnny, just following up on my earlier message. I'd love to help with your home search when you're ready. Reply END to opt out of future texts.
Best practice: If a lead has stopped responding, don't send back-to-back texts at all. Space out follow-ups, or move the lead to email-only contact. Carriers flag back-to-back one-sided texting patterns as spam regardless of whether opt-out language is included.
Two-Way Communication Decision Tree
Use this to figure out whether your next text needs opt-out language manually included:
Start: You just sent a text to your lead with opt-out messaging. What happens next?
Did the lead respond?
No → Your next text needs opt-out language. BoomTown will auto-append if enough time has passed since the last auto-insertion; otherwise, include it manually.
Yes → Continue to the next question.
Has opt-out language been sent to this lead in the last 30 days?
Yes → You can respond without needing to include opt-out language again.
No → BoomTown will auto-append opt-out language on your next text.
In practice, your primary responsibility is:
Write identification (name + company) into your first outreach.
Space out your follow-ups so you're not sending back-to-back texts to a silent lead.
Manually include opt-out language only when you're sending back-to-back follow-ups after two-way communication has broken.
What a Compliant First Text Looks Like
A complete, compliant first text includes:
Greeting that names the lead — "Hi Joe" or "Hi Sarah"
Your identification — "this is [Your Name] with [Your Company]"
A conversational message — your actual reason for reaching out
Opt-out language — BoomTown auto-appends this
Example (compliant):
Hi Joe, this is Ben Testin with the Cobblestone Group. I was just reaching out to see how your home search was going?
[BoomTown auto-appends: This part of the message is required by your mobile carrier and is sent automatically. If you prefer not to receive text messages from me just reply end]
Example (non-compliant):
Hey, are you still interested?
This lacks identification, doesn't name the lead, and reads like spam. Without the structural cues carriers use to recognize legitimate business texting, this message is likely to be flagged.
Why This Matters for Your Phone Number's Reputation
Carriers (Verizon, AT&T, T-Mobile, etc.) track how your phone number is used and assign it a reputation score. Poor reputation leads to more messages getting filtered as spam — even compliant ones.
Things that damage your reputation:
Sending first outreach without identifying yourself
Sending many similar messages in a short time
Continuing to text leads who never respond
Back-to-back texting after two-way communication has broken
Things that protect your reputation:
Identifying yourself clearly on first outreach
Letting BoomTown handle opt-out insertion automatically
Waiting for replies before following up
Moving unresponsive leads to email-only follow-up

Key Terms
Two-Way Communication — A real back-and-forth conversation between you and a lead, established when the lead replies to your text. Protects your phone number's reputation with carriers.
Broken Two-Way Communication — When a lead stops responding to your messages. Your next text to that lead should be treated like a fresh first outreach, and if you're sending back-to-back follow-ups, opt-out language must be included manually.
Opt-Out Language — Text telling the lead how to stop receiving messages. BoomTown auto-appends a compliant opt-out message that recognizes both "reply end" and "reply STOP" as opt-out keywords.
30-Day Opt-Out Clock — The timer that governs when opt-out language must appear on a text to a given lead. Resets each time an opt-out-inclusive message is sent. BoomTown manages this automatically by re-inserting opt-out text every 30 days.
Phone Number Reputation — The score mobile carriers assign to your number based on how it's been used. Low reputation increases message filtering; high reputation improves deliverability.
Carrier Filtering — When a recipient's wireless carrier blocks or filters a message as suspected spam before it reaches the recipient's phone. Often surfaced in BoomTown as "Message was flagged as spam."
Quick answers to common questions
Do I need to include my name and company in every text? No — only on first outreach, or when two-way communication has broken (lead stopped responding and you're sending another message).
Do I need to type "reply STOP" or similar on every text? No — BoomTown auto-appends opt-out language on your first text and every 30 days thereafter.
What opt-out keywords work? Both reply end and reply STOP are valid. Recipients can use either.
Does auto-append work for Smart-Drip texts too? Yes — BoomTown handles compliance timing for both manual texts and Smart-Drip text steps.
When do I need to manually include opt-out language? Only when you're sending back-to-back texts to a lead who has stopped responding (broken two-way communication). In that case, BoomTown's auto-append may not trigger.
What if I edit a text before sending and remove the opt-out text? The auto-append happens at send time, so typically you don't need to include it manually. Leave the auto-appended portion intact unless you have a specific reason to modify it.
What if the lead marks my message as spam? Their carrier will begin filtering your messages to that number. There's no way to un-flag a marked message; focus on future outreach following the compliance rules.
