Text Request provides four distinct tools to customize your outbound communications. | **Personalization Feature** | **Primary Function** | **Ideal Use Case** | | --- | --- | --- | | **Custom Signatures** | Appends sender names, titles, or business details to messages. | Individual outreach and team transparency. | | **Merge Fields** | Dynamically populates contact details (e.g., first name, appointment time). | Bulk group texting and automated reminders. | | **Emoji Characters** | Adds visual warmth and character to text conversations. | Informal updates, promotions, and friendly check-ins. | | **Image and File Attachments** | Sends photos, PDFs, or GIFs alongside text copy. | Invoices, quotes, property photos, and flyers. |   ### **Custom Signatures** Attach pre-saved personal sign-offs to your outgoing texts. Each user can create multiple signatures, set a default sign-off, or configure signatures to automatically append to every draft. **Note:** To create or edit saved signatures, navigate to **Avatar Icon** (top-right corner) \> **Profile Settings** \> **Signature**. For a complete walkthrough, view our [Custom Signatures guide](https://help.textrequest.com/custom-signatures?utm_source=gemini&hsLang=en).   **Path: Compose Message** OR **Conversation Thread \> Message Field \> Signature icon** (squiggly line) ![](https://help.textrequest.com/hs-fs/hubfs/image-png-Sep-21-2026-03-09-54-3781-PM.png?width=670&height=310&name=image-png-Sep-21-2026-03-09-54-3781-PM.png) Custom signatures count toward your total message character limit. Ensure your message text plus signature stays under 160 characters to avoid splitting your draft into multiple billed SMS segments.   ### **Merge Fields** Merge fields allow you to send personalized messages at scale by automatically pulling contact information into your text drafts. **Path:** **Compose Message** OR **Conversations** \> **Select Conversation** \> **Merge Fields** icon (brackets) ![](https://help.textrequest.com/hs-fs/hubfs/image-png-Sep-21-2026-03-14-20-6429-PM.png?width=854&height=411&name=image-png-Sep-21-2026-03-14-20-6429-PM.png) - **Standard Fields:** Automatically insert a recipient's `First Name`, `Last Name`, or `Display Name`. - **Custom Fields:** Pull specialized contact data points created from [Custom Fields](https://help.textrequest.com/custom-fields?hsLang=en) in the contact's details, such as `Account Number`, `Appointment Date`, or `Balance Due`. **Note:** When using merge fields in group messages, Text Request dynamically calculates character counts based on each contact's individual data to prevent unintended message splitting\[cite: 5, 60\]. Learn more in our [Merge Fields guide](https://help.textrequest.com/merge-fields?utm_source=gemini&hsLang=en).   ### **Emoji Characters** Emojis are a great way to give your text messages personality and make them stand out in a contact's inbox. **Path:** **Compose Message** OR **Conversations** \> **Select Conversation** \> **Smiley Face** icon **Warning:** Excessive or repetitive emojis can **trigger carrier spam filters** and cause message delivery failures. Use emojis sparingly (1–2 per message) and never repeat the same emoji consecutively. Adding an emoji also changes your message encoding to Unicode, which lowers your single segment character limit from **160 to 70 characters**.   ### **Images and Attachments (MMS)** Enhance your message by attaching photos, graphics, or document files directly to your text. **Path:** **Compose Message** OR **Conversations** \> **Select Conversation** \> **Paperclip** icon ![Add Attachment](https://help.textrequest.com/hs-fs/hubfs/Help%20Center/Add%20Attachment.gif?width=648&height=320&name=Add%20Attachment.gif) - **Supported File Types:** JPG, PNG, GIF, and PDF. - **File Size Limits:**  A single message can have up to 3 attachments of any size, but the images will be downsized until the total size is **no** **more than 5MB**. PDF files must be under **1 MB**. Sending an image or file converts your message from a standard SMS to an MMS message.
