OK, so first of all I think we need to clarify the basics and you are once talking about creating tokens, then you don't want to, etc.
So there are different options on how to provide access to your survey:
- A public survey: this means that anyone who has the link can access the survey, no restrictions. This is good when you don't know who your respondents are and you want to allow anyone to participate that has the link. So the link could be shared via email, social media, you name it. You have no control over who responds and who your respondents are, because the link can be shared by others, etc.
- Closes survey: This means people need to have the token to be able to participate. A token is like a little individual and unique code. So if someone accesses your survey they need to put the token or if you send individualized links the token can be already included in the link. Tokens can have one or more uses. Standard is one, which means once the survey has been completed with this token, it can not be completed again.
So now in your case: you want to send your survey via your normal email marketing tool to respondents. So far so good. But: do you want to allow everyone to participate? Then you can send just the normal survey link of a open survey. No need to use tokens. But you will not know who answered what, there is no way to connect results with the person (only if you ask who they are in the survey).
If you know who your participants are, the best way is to create a closed survey with individualized links. Your error message sounds like you did not create the CSV file correctly. The best way to do so is to create one user with token and everything in the system, then export this token table to CSV, have a look at the structure and build your CSV based on that. You probably did not use the correct headers or something. If you want to, you can post an example of your CSV here (e.g. a screenshot with the personal data of the respondents like name, email, etc. blurred), so we can have a look at what went wrong.
Now if you want to send individualized links, but with your own system, this is also possible, you just can't use the bounce system and the reminders. There is an example in the manual on how to create a a list of individualized links with excel (
www.limesurvey.org/manual/Tokens/en#A_ti...de_the_token_already
). You can feed these links into your Email system then.
But first of all, it would be important that you explain clearly what your ideal approach would be and we can suggest options from there. You are jumping back and forth and it is not clear for us, what you have, what you need, etc.
