SMS Surveys allow you to send your AskNicely survey via text message. We typically recommend implementing SMS once you have gotten up and running with a "Touch Base" emailed survey to all of your customers. However, if you don't capture email addresses or if text is your primary method of communication, starting with SMS is a great option.
If you're interested in adding SMS to your account, please contact your Customer Success Manager or Account Executive for SMS pricing. Plans vary based on location and survey limits, and several back-end changes must be enabled on your account before you can proceed.
📞 Number Formatting Guidelines
🧠 Know Before You Go
- The number of SMS that you purchase is an estimate based on cost per message, not the number of surveys you can send. Initial message, SMS Workflow messages, and SMS Workflow responses all count towards the message limit. If an SMS is more than 153 characters including the survey URL, it will be split out and count as more than one SMS. The same goes for any reply you may receive or any workflows. (see FAQ's below for URL length)
- You get $10/USD worth of free SMS messages when you initially sign up, allowing you the opportunity to test and check for validity.
- If you are using the API to bring your contacts into AskNicely, SMS messages do not follow the "delayminutes" rule.
-
If SMS is your primary survey method, that's great! We can do that as the only way of delivering surveys, or we can set it up where SMS is the initial method and email is the fallback.
-
What AskNicely cannot do:
- Send an email survey initially, then send a follow-up via SMS.
-
What AskNicely cannot do:
Important: AskNicely cannot send an email survey first and then follow up with SMS.
📲 The SMS Survey Experience
Survey invitations are sent from a U.S. phone number and contain a link to your survey. When the recipient taps the link, it opens in their mobile browser.
Once the score is selected, any Feedback Topics or Conversation fields will be displayed as configured.
Easy and mobile-friendly for the respondent!
🛠️ Account Setup for SMS
Contact your AskNicely CSM or Account Executive to enable SMS. You can also head to AskNicely's App Store > search "Send SMS surveys" > click the button to request SMS

API Methods
Method 1: Shared Field
If you are using the same API call to bring in both Email and SMS Contact information, the phone number needs to be formatted as described above; in addition, "@sms.asknice.ly" needs to be appended to the end of the number as well.
Example:
If the phone number for a contact is "1 (855) 867-5309"
Method 2: Dedicated Mobile Field
If you are using a unique field for SMS, our Support Team can direct SMS sending based on that field. Formatting of the API call would therefore look like:
Contact support@asknice.ly if you need setup help.
📥 CSV Column Mapping Options
Option 1 – Primary Survey Method (Recommended)
-
Match your SMS field to: Mobile Number (Primary Survey Method).
- Note: If you don’t see the “Mobile Number (Primary Survey Method)” option, ask support@asknice.ly to enable SMS for your account.
Set this during CSV import or via supported integrations like Salesforce.
Option 2 – Fallback to Email
Import both "Email" and "Mobile" fields.
SMS will be sent first; if it fails, fallback to email.
- Import the email as the AskNicely field "Email."
You will then the contact's SMS number as its own "Custom Data" column, so if your field is "mobile_number", it would be "Custom Data > Import as: "mobile_number."
- The phone number should be in that column & formatted correctly.
Contact support@asknice.ly to activate fallback logic for this field.
✏️ Build Your SMS Template
Go to the Survey page and choose your template.
Click the SMS tab to edit the message body.
Test your character limit by clicking here. Select the "auto" option below the text box when checking total message count. If you leave it on the default of "gsm" it will highlight in red the characters that would cause a message to break into two separate texts automatically. Using special characters can drastically change the total character count.
Short messages ensure surveys stay within one SMS.
🔗 SMS Shortlinks
If your account has multiple brands, enable SMS shortlinks to replace your domain with a generic s URL for simpler display.
📤 Schedule & Send SMS Surveys
Use the Send Page (paper airplane icon) to schedule daily sends.
Use the Email button on the Contacts page to manually send an instant SMS to a single Contact.
API & integration triggers can send SMS based on events (contact your CSM).
🔀 Sending Email + SMS from One Account
Yes! AskNicely can send surveys via either SMS or Email, or use SMS first and fall back to email.
Be careful: if a contact exists under both email and SMS as primary identifiers, they may be treated as two separate contacts.
❓FAQs
Q: Why is my SMS balance running out even though I haven't sent my survey limit?
A: SMS is paid for not by number of surveys, but by number of messages sent. Your initial message, SMS Workflow messages, and SMS Workflow responses all count towards the message limit. Long messages may be split into more than one SMS.
Q: How do I know if a message will be split?
A:SMS messages split at 153 characters. When we're talking about your initial survey message, that includes both the text asking recipients to complete the survey and the link to the survey. The message includes a URL automatically.
Remember that Dynamic Fields are variable, too, so if your message contains {firstname}, you should plan for long names, which will increase the character count.
Remember, short messages are your friend in SMS!
Q: Will someone be double-surveyed, once by SMS and once by email?
A: Not if you use a custom field with phone number instead of putting the phone number in place of the email address. Because we use email address as a unique ID, if you add the same user but put their phone number in place of their email address, it would be considered a new user that's unaffiliated with the first. If that happens, someone may get double-surveyed.
Q: What if the phone number is incorrect and is actually a landline?
A: According to our sending service, US, UK, and Canadian landline numbers may be eligible to receive SMS (via automated voice recording).
For all other countries, we will get a "failure to deliver" notice and an email survey will be attempted only if you have an email address attached to the Contact Record.
To avoid this scenario at all, please double check the phone numbers you are importing.
Q: Which performs better — email or SMS?
A: Both are similar, but email surveys tend to have longer comments.
Q: Do SMS surveys count toward our overall monthly/annual survey limits with emailed surveys or inapp Web Surveys?
A: Yes, SMS surveys count toward your total survey limit.
Q: Can I use SMS with Workflows?
A: Yes! See the SMS Workflows and Alerts help article for details.
Q: Can I change the sending phone number?
A: No, numbers are managed by Twilio and cannot be customized.
Q: Is there a character limit for SMS responses?
A: Yes. Individual replies are limited to 160 characters. Longer replies are split and capped at 320 characters (2 messages).
