Does Dedupely work with Attio?

No. As of September 2026 Dedupely lists integrations with HubSpot, Salesforce, Pipedrive, Close, Nimble and Google Contacts, plus CSV. Attio is not among its supported systems.

What is the Attio equivalent of Dedupely?

Deduptio. It performs the same job — configurable merge rules per object, duplicate groups, bulk merging, control over which values survive — against an Attio workspace, using Attio's own record merge so activity history follows the surviving record.

How does the pricing compare?

Dedupely prices by record count: as of September 2026 its Basic plan is $19 per month or $300 per year for up to 30,000 CRM records, and Enterprise is $1,000 per month for up to 1,500,000 records, with all features on every plan. Deduptio has a free plan with 25 live merges a month on objects up to 10,000 records, and Pro at $59 per month covering objects up to 100,000 records with unlimited merges.

Can Dedupely clean an Attio CSV export?

Dedupely supports CSV as a source, so it can identify duplicates in an exported file. That does not clean Attio: removing rows from a file changes nothing in the workspace, and re-importing a cleaned CSV creates or updates records but never deletes them. The merge has to happen against the live Attio records.

Dedupely alternative for Attio

Dedupely is a well-established CRM deduplication tool with strong marketplace ratings on HubSpot, Salesforce and Pipedrive. It also supports Close, Nimble, Google Contacts and CSV. What it does not support is Attio.

The short version: if you liked how Dedupely worked, Deduptio is the same shape of tool for Attio — rules you define, groups you review, merges in bulk, control over what survives. The differences are Attio-specific rather than philosophical.

Where the price comparison actually lands

Dedupely is cheaper at the small end — $19 a month for up to 30,000 records is hard to beat, and Deduptio's free plan is capped at 25 live merges a month rather than being unlimited. If your whole problem is a few dozen duplicates a month in a small workspace, the honest answer is that either tool's entry tier is inexpensive and the deciding factor is which one connects to your CRM. Dedupely does not connect to Attio, which settles it — but the price point is worth stating plainly rather than pretending flat pricing wins everywhere.

Deduptio's flat $59 stops moving as the workspace grows, up to 100,000 records per object. Record-count tiers reprice you as you succeed.

What is different because it is Attio

The merge is Attio's.Deduptio calls Attio's own record merge rather than assembling a surviving record itself, so the outcome matches what you would get merging by hand in the interface.
Attio's merge cannot be undone. A record deleted by a merge cannot be recovered by you or your team. Every Deduptio merge is snapshotted first, giving a 24-hour window — with documented limits on what the restore re-creates.
Lists are their own problem. Attio lists can hold the same record twice, and merging duplicates is the usual way that happens. Deduptio cleans those entries with the same restore window — see duplicate list entries.
Deals and custom objects.Attio's own merge covers people and companies only; match rules and merges in Deduptio apply to any object.

Still running the old CRM too?

Keep Dedupely pointed at it. The two tools never touch the same records. What does need attention is whatever moves data between the systems during a transition: make sure it matches on a unique attribute — email for people, domain for companies — so a sync does not rebuild in Attio the duplicates you just cleared elsewhere.

See what is duplicated before changing anything

Connect your Attio workspace, write one match rule, and run a scan. Scans are read-only — you see every group and the reason it matched before anything is merged.
