I live in a bilingual country and in my bilingual invitation email I need to invite participants to take part in slightly differently-worded questionnaires, depending on which language(s) their company communicates in and which language is their choice to reply in: a total of 6 questionnaires.

Viz:
the company produces communications in English only (choose to reply to an English-language questionnaire)
they produce communication in English only (choose to reply to a Welsh-language questionnaire)
and so on for companies that communicate in Welsh only, and those that communicate in both English and Welsh.

I've just spent a day setting up a survey on Survey Monkey, to then find that I can only have one weblink from my invitation email. I am frustrated, as I am a micro-business trying to do market research on a practically £0 budget.

I would include all this in the questionnaire.

I would ask them which of the 6 different types they are and then only show the relevant questions for their type (via conditions).

Advantage: you have everything in one survey.
Downside: you have everything in one survey.



You can probably include the links into the invitation email manually. But I have never tried this.
