Snap XMP lets you bring multiple systems together with two-way database links and an API.
When you already have data on your contacts (such as a unique ID, name, or gender information), this information can be fed directly into a survey.
By personalising your surveys to respondents, they find it more relevant to themselves and are more likely to respond. It can also hold their interest and keep them engaged, leading to more considered answers and better-quality data.
It can also shorten the survey by pre-answering any questions you already know the answer to due to the data you hold.
