Text messages have open rates above 90%. If you need people to actually see your survey invitation and respond, SMS is the channel. BlockSurvey brings this reach to your existing survey workflow.
Most text campaign tools store your contact list and message content on their servers. BlockSurvey's end-to-end encryption means your audience data and campaign content stay private, no third party can read them, including us.
BlockSurvey already powers your email campaigns. Text campaigns use the same audience lists, the same survey links, and the same campaign builder, no new tool to learn, no extra setup.
Send a single text message to your entire audience at once. Perfect for one-time surveys, announcements, event feedback, or fundraising appeals. Schedule it in advance or send it immediately, every recipient gets the same message at the same time.

Automate a sequence of text messages sent over time. Set trigger conditions, define delays between messages, and let BlockSurvey handle follow-ups automatically. Ideal for onboarding sequences, longitudinal research, patient engagement, and fundraising journeys.

Automatically send a follow-up text only to contacts who haven't completed the survey. No manual filtering, no awkward blanket reminders, just a targeted nudge to the right people at the right time. Learn how to create a Text Campaign.

Survey your customers where they already are. Text-based NPS, CSAT, and product feedback surveys get higher response rates than email. Drip campaigns let you automate the full feedback sequence, from initial invite to final follow-up.
Text message fundraising campaigns get donations. SMS reaches supporters directly, no inbox clutter, no algorithms. Send a campaign, collect responses, and follow up with non-donors automatically. All without exposing your supporter list to third parties.
Collect real-time feedback from attendees during or immediately after an event, while the experience is still fresh. Bulk SMS gets your survey in front of every attendee at once, and drip follow-ups keep the conversation going after the event ends.
Reach study participants where response rates are highest. Send survey invitations, reminders, and follow-up questionnaires by text — without exposing participant contact details to third parties. End-to-end encryption keeps sensitive research data protected from collection to analysis.
Send appointment feedback surveys, post-treatment check-ins, and patient satisfaction questionnaires directly to a patient's phone. HIPAA-compliant by design, so sensitive health data stays protected at every step.
Mobilise your base with targeted text campaigns. Collect constituent feedback, gauge support, and follow up with volunteers, all through a private, encrypted channel that keeps your contact data under your control.
Start free. Upgrade when your research outgrows it. Every plan keeps end-to-end encryption and full data ownership.
