Hi,

I am brand new to odoo.  I am only using the free online CRM version which comes with the contacts app.  I am trying to import my contacts, and there seems to be no way to avoid importing duplicates.  I am wanting to avoid duplicates when the email address matches.  I did see that I can export my current contacts which will have an ID and then those won't duplicate when imported, but unfortunately, I have a list of many other contacts that don't yet have IDs and so there will be duplicates there. 

I have seen on Google that there are some third-party solutions, and also some posts that recommend using python scripting, but I'm not sure if any of that is possible with my free plan.  Am I able to avoid duplicates based on email with the free plan?  If not, am I able to use the standard plan (which does not include Studio) and achieve this?  Thank you.
