Hello,
I would like to get assistance in Synchronizing my old emails with hubspot so I can add the senders as contacts. The company’s email server is IMAP (not exchange nor outlook). What is the best way to achieve this.
Thank you for your help
Hi Karsten,
Thank you for getting back.
We don’t have a Threads account, is there any other way to do it.
Hi @AYazbeck,
If you export all of your emails from your existing account, along with contact information (at least the Email of the contact), you can then import contacts + emails: Format import files
The import file would have to have columns for the contact’s email address, the email direction and the email body at the very minimum.
It’s important that you import both objects at the same time and that there aren’t any mistakes. It’s not possible to turn back time on imports or bulk delete imported activities. When in doubt, start by importing only a few lines of your file.
Since this can be a complicated process, some app providers have decided to faciliate the process but charge for it (Threads).
@karstenkoehler side note - I’d much rather have an app like Threads do it rather than try it on my own. Or just not worry about old emails from a previous system. But maybe that menas I’m lazy 
Hi @AYazbeck,
Good news, there’s now a dedicated product update for this 
For now, this is feature is available for Gmail accounts only but that might change.
Historical email import
What is it?
Please not it is supported for Gmail only for this rollout
Historical email import is a new powerful onboarding tool that allows users to bring in contacts and old email threads from their inbox to HubSpot so they can easily continue their prospecting efforts in the new CRM.
Why does it matter?
Starting from scratch in a new system is hard. By importing in all your existing context to your CRM, you can pick right up where you left off but using HubSpot’s powerful tools.
How does it work?
After connecting a personal email, use the Actions drop down menu to select “Import historical data”. This will guide you through a flow where you can define your date range, choose to import emails for existing contacts or create new contacts as well.
Admins can turn this feature on or off and set defaults in Email Log & Track settings.
