Use the open link when anyone who has the address can answer. For a closed survey, add people to the participant list and give them access codes. Each code can have a limit on how many times it can be used.

If you want to follow up with people who haven’t answered without seeing how each person replied, review the anonymized responses setting before activation. It separates the answers from the invitation record. Before activation, open Settings → Notifications & data and review the separate switches for saving IP addresses, the page someone came from, submission dates and time spent on each page. Turn off collection you don’t need. Those settings lock when you activate the survey. Avoid asking for names or other details that would identify people in the answers themselves.

Where do the answers live and what can you move?

LimeSurvey Cloud hosts the survey for you. Community Edition runs on a server and database you manage. In Cloud, the Results tab lets you export responses as CSV or other supported formats and choose whether to include incomplete responses.

A response export helps you analyze answers elsewhere. For a self-hosted move, keep the database and installation files too, including uploads that are outside the database backup. Plan who will do updates and prove a backup can be restored before collecting information you cannot replace.

How do you test an invitation and the final screen?

Start with a disposable survey and invented questions and participants. Before activating or opening it, confirm there is no real participant list, mail delivery, integration or production redirect connected. If you can’t confirm that, review the configuration without activating the survey.

Prepare a closed sample
In Share, choose Link with access code and open Participant lists. Create one dummy participant and copy its generated code. Leave public registration and confirmation emails off. Keep the link and code for your own check.
Choose the ending before testing
Set an end message and, if useful, enter a test page you control in End URL. Add a URL description to show the destination as a button. For an automatic redirect instead, turn on Automatically load end URL in Presentation under Navigation.
Try the link with and without the code
Activate the isolated survey. Open the general sample link in a private window and check that it asks for a code. Enter the dummy code and send made-up answers. You should see the end message and any button you configured, or arrive directly at the test page if automatic loading is on.
Check the saved answer
Find the response in Results and see whether your export contains what you expect, including how it represents an incomplete answer if you plan to use those.

What changes the cost of running a survey?

Cloud plans count responses over their plan period. The subscription help lists Free at 25 responses per month. Basic has a monthly allowance, while Expert and Business have annual allowances.

Community Edition is the free software you host yourself. Its costs can include the server, storage and the time to update the software and restore backups.
