Can you give an example of where you’re unsure? Mapping is very contextual to each portal.

As long as you have the email address mapped, HubSpot will automatically deduplicate by email address. Deduplicate records in HubSpot

You would map them during the mapping process and HubSpot should tell you whether everything looks good by showing a green checkmark. If anything is off, HubSpot will point that out to you. If you have a specific example, feel free to share a screenshot of a mapping you’re unsure of.

HubSpot will perform checks during the mapping process already. If anything is wrong and HubSpot cannot fulfill what you’re trying to map, there’s going to be an error message. In terms of your data being incomplete or accurate, HubSpot cannot do anything about this, unfortunately. There is a saying in a lot of industries; “garbage in, garbage out”. You would have to make sure that whatever you’re feeding HubSpot is correct and up to date. HubSpot cannot do this for you, unfortunately. If you assume that you’re data is outdated, incorrect, incomplete, it’s better to review the import data outside of HubSpot first.

Typically, each import file is a bit different and especially if you’re new to this process, I’d recommend going through the process slowly, reading the instructions carefully to avoid any problems. There isn’t a reverse / back button for imports. If you have the same format in your import file every week or month, HubSpot does let you use an import template. Just watch out for that option during the import wizard. HubSpot will suggest mappings based on your previous imports then. You can also reduce the risk during the import process by naming the columns in your import file exactly like the HubSpot properties.

As a general tip, if you don’t feel comfortable yet, don’t start by importing 1,000, 10,000 or 100,000 at once. Nothing’s stopping you from mapping just 5 rows of your import file and checking the import and whether everything went well. If all looks good, you can still import the rest. This reduces the potential need for clean-up, should anything go wrong.

Let me know if you have any follow-up questions!
