+1 (would +infinity if I could).
We have many accounts in our database that have multiple email domains (.com vs .co.uk; XYZusa.com vs XYZ.com; etc.). We CANNOT merge these accounts due to our integration with SFDC (which is another huge headache). It is an endless uphill battle to try and keep our data clean/fight these duplicate accounts.
It has been years since this idea was first submitted, with no reply from HubSpot. This issue may cause my organization to switch providers as it is a waste of valuable time and resources to keep cleaning the same data over and over again. HubSpot, please fix this issue!
