Why did you append opt out option to my SMS?

Why did you append opt out option to my SMS?

Short answer: To comply with Indian telecom regulations (TRAI/DLT), MyOperator automatically appends an opt‑out instruction (e.g., “Reply STOP to unsubscribe.”) to eligible outbound SMS so recipients can easily stop promotional or service‑explicit messaging. This helps prevent filtering/penalties and protects deliverability.

What it is and why it’s required

  • TRAI/DLT rules require a clear opt‑out mechanism on promotional or similar non‑personal SMS.
  • MyOperator automatically appends a short opt‑out line on applicable routes so you remain compliant and maximize deliverability.

When the opt‑out is appended

Actual behavior depends on your route/category/template. Use Preview to see the final message before sending.

Message type / route

Opt‑out behavior

Promotional / Service‑Explicit (bulk, automated outreach)

Appended (mandatory)

Transactional / OTP (alerts, one‑time passcodes)

Typically not appended

1:1 responses (agent replies)

May not be appended; depends on route/category

Regional language sends

Appended; text may be localized where supported, otherwise English

If your content or header/template causes reclassification to a promotional route, the opt‑out will be appended even if you expected otherwise.

Character counting and billing

  • Carriers bill by segments (GSM‑7 ~160 chars/segment; UCS‑2 ~70 chars/segment).
  • The final sent text (your body plus the appended opt‑out) determines segmentation.
  • Long URLs, emojis, or non‑GSM characters can switch the encoding to UCS‑2 and reduce characters per segment.
  • Use the composer’s character counter/estimator and Preview to confirm total segments before sending.

Tip: If the opt‑out pushes you over a segment boundary, shorten the main message, avoid emojis, or use a branded short URL.

Preview and test

  1. Compose your SMS in Campaigns → SMS (or the message composer).
  2. Click Preview to view the final text with the opt‑out line.
  3. Send a test to your own number on at least two carriers (if possible).
  4. After sending a live campaign, open Reports to review delivery and any filtering.

Examples

You write

ACME: We noticed a missed call. Book a callback: acme.co/cb

Sent (final)

ACME: We noticed a missed call. Book a callback: acme.co/cbReply STOP to unsubscribe.

Regional language example (body in Hindi; opt‑out may be localized where supported)

ACME: हमने आपका मिस्ड कॉल नोट किया है। यहाँ बुक करें: acme.co/cbReply STOP to unsubscribe.

Customization/removal

  • The opt‑out clause is mandatory on eligible routes and cannot be removed or edited.
  • Avoid adding your own opt‑out inside the message body (it can cause duplication). Rely on the automatic line and use Preview to confirm.

Troubleshooting

  • Opt‑out didn’t appear: Your message likely used a transactional/OTP or non‑promotional route. Check the header/template category and the Preview.
  • Opt‑out appeared twice: Remove the manual line from your body; rely on the automatic append.
  • Message was filtered or delayed: Ensure your DLT registration, headers, and templates are approved and match the content; avoid restricted URL shorteners.
  • Unexpected extra segments: The appended line or non‑GSM characters pushed the text over a boundary—shorten the body or adjust encoding.
