Every bulk upload is logged. Import history is the answer to "where did these contacts come from" and "did that file actually work". It is also where you fix an upload after the fact: undo it, or change its tags.

#Getting there

From Accounts → Bulk Upload → Import History, or by clicking View Details on the notification you get when an import finishes. View Details also shows the tag applied to that run and its own Merged records list.

Only your own uploads

You can only see and change your own import history.

#Two tabs

Tab	Holds
Can be managed	Uploads that still have contacts. These have Undo upload and Manage tags
Log only	Uploads with nothing left to act on, with the reason shown

Log only reason	Means
All merged	Every row was merged into an existing contact, so the upload created nobody new
All failed	No row made it in
Nothing imported	The upload created no contacts
Already deleted	The contacts it created have since been removed
Details not saved	An upload from before 28 October 2026, recorded without the details undo needs

Your most recent upload is marked Latest.

#What each entry shows

Field	Means
File name	What you uploaded
Total records	Rows in the file
Imported	Contacts successfully created
Failed	Rows that did not make it, with the reason
Auto-generated values	Contacts imported with a generated name, or flagged Cannot be contacted because the row had no real email or phone at all
Merged	Rows that matched an existing account closely enough to be merged into it rather than imported as new. The tag choice used for the merge is recorded too
Completed	When it finished

#What to check after an import

1
Does imported plus failed equal your total?
If not, and your file was over 2,000 rows, the rest was left behind. See Bulk upload.
2
How many are flagged Cannot be contacted?
Those rows had no email or phone at all, nothing was invented to fill the gap. Fix them from Accounts list → Email Updates.
3
Read the failures.
They are usually one systematic problem rather than many individual ones.

#Undoing an upload

Uploaded the wrong file? Undo upload removes the contacts that upload created, so it no longer needs a support request to clean up.

Contact	On undo
Created by this upload	Deleted
Already existed, merged or skipped as a duplicate	Never touched
Created by a different upload, even with the same name or email	Never touched
Linked to a listing, an opportunity or an active campaign	Skipped, not deleted, with the reason shown

1
Open Accounts → Bulk Upload → Import History.
2
On the upload, click Undo upload.
3
Check the Eligible and Skipped lists, then confirm.
Eligible contacts will be deleted. Each skipped contact shows why it is being kept.
4
Keep the window open while the progress bar runs.
An upload holds up to 2,000 contacts, and undo handles them all. Closing the window stops it partway; run Undo again to finish.

Result	What happens to the entry
Full undo	Moves to the Log only tab and is marked as just undone
Some contacts skipped	Stays in Can be managed, so you can run Undo again later, once those contacts are free

Undo cannot be reversed

Deleted contacts are gone. To get them back, upload the file again. Uploads from before 28 October 2026 may show *Details not saved* in Log only and cannot be undone.

#Adding or removing tags on a past upload

Uploaded a file without tags, or with the wrong ones? Manage tags fixes it without deleting and re-uploading.

Action	What it does
Add tags	Pick existing tags or create a new one, and apply them to all or some of the upload's contacts. Different groups can get different tags. New tags are added to the ones a contact already has, never replacing them
Remove tags	Take specific tags off selected contacts, or use Delete all assigned tags

Lead always stays

The Lead tag cannot be removed. Large selections are updated in batches, with a loader while the tags are applied.

#Deleting a history entry

Deleting an entry, single, several selected, or delete-all, removes only the log. Your contacts stay in Accounts, and the message says so. To remove the contacts an upload created, use Undo upload before deleting its entry.

Deleting history never deletes contacts

Removing the contacts themselves is always a separate, explicit step: Undo upload here, or Bulk Delete Accounts on the Accounts list.
