FAQ & Support Guide
Getting Started with SMS & MMS
Can I Send MMS?
Yes! MMS is supported, but it is typically restricted to US and Canadian phone numbers. For providers like Ytel, specific numbers require manual approval before MMS can be sent. Mobile carriers apply stricter rules to MMS due to its higher bandwidth demands compared to standard SMS.
Best Practices for Bulk MMS
To avoid carrier restrictions when sending MMS at scale, assign multiple phone numbers to your account and enable the rotation feature. This distributes message volume across various outgoing numbers, reducing the risk of throttling or delivery failures.
Real-World MMS Use Cases
Realtors are a great example — they use MMS for auto-replies to new subscribers who text a keyword to receive property details. Once subscribed, follow-up updates switch to regular SMS, balancing rich media engagement with efficient ongoing communication.
Ensuring Compliance and Best Practices
Staying compliant with SMS regulations is not optional — it protects your business and your customers. Here are the key rules every sender must follow.
Mandatory Requirements
Opt-Out in Every Message
Regulatory rules require that every message include an opt-out option, such as "Reply STOP to opt-out." This is non-negotiable and must appear consistently.
No Unsolicited Rates or Pricing
Avoid mentioning specific rates or monetary amounts unless the customer has directly inquired. Keep messaging focused on their expressed interest.
MMS Content Standards
All MMS content must include your business name, a clear reference to the customer's inquiry, opt-out instructions, and relevant, professional media.
Tips for Effective Messaging
Write Engaging Messages
Use personalized language, ask open-ended questions, and keep the focus on the customer's needs. Avoid overly promotional or sales-heavy language.
Avoid Links in First Messages
Links in initial messages can be flagged as spam. Provide essential information directly and invite the recipient to reach out for more details.
Consequences of Non-Compliance
Violations can result in suspended messaging privileges, temporary downtime, financial fines, and lasting damage to your brand's reputation.
Customizing Your SMS Experience
Preparified gives you powerful tools to tailor how your messages look, feel, and reach your audience. From sender identity to personalized templates, here's what you can configure.
Sender ID
If your country supports alphanumeric sender IDs, you may be able to display your company name instead of a phone number. This typically requires pre-registration with your SMS gateway provider and admin approval.
SMS Templates
Templates define your message structure using predetermined content and variable placeholders (e.g., {#var#}). This makes it easy to send consistent, personalized messages to many contacts efficiently.
Template Approval & DLT
Certain services require DLT (Distributed Ledger Technology) Template IDs for approval — especially for OTP (One-Time Password) messages. This ensures priority delivery and regulatory compliance on supported carriers.
Personalization
Customize templates using account, contact, or ticket fields, with default values if a field is blank. Example: "Hello [Contact Name], you provided [Phone Number] for SMS communication. Confirm by replying START. To opt-out, reply STOP."
