One campaign. Each contact
reads it as their own.
Dynamic keywords personalize one bulk SMS campaign for each contact using fields such as name, location, last service, rep name, and offer amount. Write the message once, then send a tailored version to the full list.

Why personalization changes response rates
Generic bulk SMS gets ignored.
Personalized SMS gets replies.
A message that starts with “Hi [First Name]” from a number they recognize, referencing their last interaction, usually performs better than a generic broadcast. Dynamic keywords can place fields such as name, city, last service date, rep name, offer amount, or vehicle make directly into the message. Use one template to create tailored messages at scale without manual editing.
👤
Name-based personalization
Insert first name, last name, or company name. “Hi [First Name], it’s [Rep Name] at [Company]” reads like an individual message because each contact receives their own data.
📍
Location-based personalization
Insert city, ZIP code, region, or territory. Local references such as “customers in [City]” or “available in [ZIP]” make the message feel relevant to the recipient.
🔄
Behavior-based personalization
Reference last service, last purchase, or last inquiry. “Since your [Last Service] in [Month]” shows that the message is based on their history rather than a cold list.
💬
Example dynamic message
“Hi [First Name], it’s [Rep Name] at [Company]. It’s been a while since your [Last Service]. We’re running [Offer] this [Month]. Interested? Reply YES or STOP to opt out.”
Write it once. Each contact receives a version with their data filled in. OTTO routes YES replies to qualification and STOP replies to opt-out.

Questions aboutdynamic keyword campaigns.
What happens if a dynamic field is missing for a contact?
You configure a fallback value for each dynamic field before sending. For example, if no first name is on file, the fallback might be “there” (“Hi there” instead of “Hi David”). TextingOnly previews a sample of resolved messages before any send so you can catch missing or incorrect fields in advance.
How many contacts can I send to at once?
TextingOnly can support lists ranging from a few hundred contacts to larger campaigns. Delivery is staggered to comply with carrier requirements and protect your 10DLC sender reputation. Large sends are queued and dispatched automatically without manual management.
Can I track performance by dynamic field segment?
Yes. You can segment campaign performance reporting by city, rep, service type, offer amount, or another mapped field. This lets you identify which segment responded best and optimize future sends accordingly. Cost per engaged contact is trackable per segment.
Does OTTO automatically handle replies from a bulk send?
Yes. Replies to a dynamic keyword campaign route through OTTO. YES or positive replies trigger qualification and a contact alert to your team. STOP triggers instant TCPA-compliant opt-out. Non-responders can be enrolled in an automated follow-up sequence at your configured interval. This reduces the need for manual monitoring.

Mass Texting with Dynamic Keyword Personalization
How does TextingOnly handle personalized mass texting with dynamic keywords?
TextingOnly imports your contact list, CRM export, spreadsheet, or direct upload, and maps each column to a dynamic keyword field: first name, last service date, rep name, city, offer amount, vehicle make, or any other field in your data. One message template is written once with placeholders. At send time, each contact receives their own individually rendered version with their specific data filled in. OTTO routes each reply, YES to a qualification flow, STOP to immediate TCPA (Telephone Consumer Protection Act) opt-out, silence to a configured follow-up sequence. Delivery runs on 10DLC (10-digit long code) registered numbers with staggered carrier-compliant dispatch.
What happens if a dynamic keyword field is missing for a contact?
Before any send, TextingOnly generates a preview of resolved messages across a sample of your contact list. Any contact with a missing field value is flagged in the preview so you can review before deployment. For each dynamic field, you configure a fallback value that renders when the contact’s data is blank, “there” instead of a first name, “your area” instead of a city, or a default offer amount. The preview step ensures no contact receives a message with an unfilled placeholder or a broken field reference. The send is blocked until all required fields have either populated data or a configured fallback.
How many contacts can I send to at once with TextingOnly?
TextingOnly sends to contact lists of any size, from a few hundred to tens of thousands in a single campaign. Delivery is staggered in compliance with carrier throughput requirements and to protect your 10DLC (10-digit long code) sender reputation. Large sends are queued and dispatched without manual management. Staggered delivery does not affect personalization, each contact receives their individually rendered message with dynamic fields resolved to their specific data. Campaign performance tracking updates as messages deliver and replies arrive. Per-segment reporting breaks performance by dynamic field value, city, rep, service type, or offer amount, so you see which segment drove the most engagement.
