Is Sigmera an alternative to Dedupely?

Only for part of the job. Sigmera deduplicates a CSV before it is imported; Dedupely deduplicates records already in a CRM. If your problem is a messy file on your desktop, Sigmera replaces the need for Dedupely entirely. If your problem is 4,000 duplicate contacts in HubSpot, Sigmera cannot help — it has no connection to your CRM.

Can Dedupely deduplicate a CSV file?

Yes. Dedupely supports CSV uploads, positioned as a way to test merge logic before running it against a live CRM, and that path does not require a CRM connection. The difference from Sigmera is where the file goes: uploading a CSV to Dedupely means sending the records to their service, while Sigmera reads the file inside your browser tab and never transmits it.

Can Sigmera remove duplicates that are already in HubSpot?

No. Sigmera has no integration with any CRM and never sees your account — it only reads the file you open in the browser. To clean records already in HubSpot you need a tool that connects to it, such as Dedupely or HubSpot's own duplicate management. Sigmera's role is making sure the next import does not add to the pile.

Which one is cheaper?

They are priced on different things, so it depends on your database size. Sigmera is free for 3 downloads a month, $15 for 30, and $39 for unlimited, with no row or file-size cap. Dedupely charges by synced CRM records: $19 a month up to 30,000 records, rising to $1,000 a month at up to 1,500,000, with unlimited users and merges on every plan.

Do fuzzy duplicates like "Bob" and "Robert" get caught?

By Dedupely, yes — it offers exact and fuzzy matching on the fields you choose. By Sigmera, no. Sigmera matches exact values in a selected column, so it catches duplicates that differ only in case or whitespace but treats "Bob Smith" and "Robert Smith" as two people. Normalise the column first if you need those grouped.

Does it make sense to use both?

For a team running a CRM, yes, and they barely overlap. Sigmera handles the file on the way in, so imports stop being a source of duplicates and the phone and email formats arrive consistent. Dedupely handles the records already inside, where fuzzy matching and per-field merge rules are the only things that will fix them. The first is a habit; the second is a service.

Sigmera vs Dedupely

Dedupely is a CRM deduplication service that finds and merges duplicate records already sitting in HubSpot, Salesforce, or Pipedrive. You connect it to the CRM, configure match options on native or custom fields, and it groups likely duplicates using exact or fuzzy matching. Merging can be manual with a review step, done in bulk, or scheduled to run automatically against rules you set. Its field-level merge rules decide which value survives per field — most recently updated, non-blank over blank, or custom logic — rather than discarding a whole losing record. It handles contacts, companies, deals, and custom objects. Pricing is by the number of synced CRM records, not by merges performed: Basic is $19 USD/month for up to 30,000 records and Enterprise is $1,000/month for up to 1,500,000, with unlimited users, integrations, and merge rules on every plan, and a free trial that includes 20 merges with no credit card.

Where Sigmera wins

The file is never transmitted
Sigmera parses and deduplicates inside the browser tab, so a contact list never reaches our servers. There is no processor to name in a GDPR record of processing and no transfer to assess, because there is no transfer. Dedupely, by design, must read your CRM records to compare them — a reasonable trade for what it does, but a data-processing relationship you have to document.
It stops duplicates before they exist
Dedupely is remedial: it fixes duplicates that are already in the CRM, where they have had time to split a customer's history across two records and to fire automations twice. Cleaning the CSV first means the CRM never receives the second copy. The two approaches are not in competition so much as sequential, and the cheaper half is the one that happens before the import.
No CRM and no authorisation required
Sigmera needs nothing but a file. There is no OAuth grant, no admin approval for an app with write access to every contact record, and no procurement conversation — which matters when the messy export came from a survey tool, a payroll system, or a spreadsheet a colleague emailed you, none of which are CRMs at all.
Price does not scale with your database
Sigmera charges for downloads: $0 for 3 a month, $15 for 30, $39 for unlimited, with unlimited rows and file size on every plan. A 400,000-row file costs the same as a 400-row one. Dedupely prices on synced CRM records, so the same work costs $19 a month at 30,000 records and $1,000 a month at 1.5 million.
The rest of the clean-up is in the same place
Duplicates are rarely the only defect in an export. Sigmera also standardises phone numbers to E.164, lowercases and trims email columns, splits or combines name fields, and converts between CSV and Excel — all in the same browser session, all before anything is imported. Dedupely deliberately does one job, so those fixes still need another tool.

Where Dedupely wins

Fuzzy matching that Sigmera does not attempt
Dedupely matches on exact or similar values across native and custom fields, so it can group "Bob Smith" with "Robert Smith" or catch a company recorded twice with different punctuation. Sigmera deduplicates on exact values in a chosen column. If your duplicates differ in spelling rather than in whitespace or case, Dedupely is the tool that finds them.
It can fix the duplicates you already have
This is the decisive difference. Once a duplicate is inside HubSpot, Salesforce, or Pipedrive, no file-based tool can reach it — Sigmera cannot see your CRM and never will. Dedupely connects, scans, and merges in place across contacts, companies, deals, and custom objects. For an existing mess, it is doing something Sigmera structurally cannot.
Field-level merge rules instead of a surviving row
When two records both hold real information, picking a winner loses data. Dedupely applies rules per field — keep the most recently updated value, prefer a populated field over a blank one, or custom logic — and highlights which value will survive before you confirm. Sigmera's dedupe keeps a row and drops the other, which is the right behaviour for a raw import file and the wrong one for two records a team has both been editing for a year.
Continuous, automatic hygiene
Duplicates in a live CRM are a flow, not a one-off: forms, imports, and integrations keep creating them. Dedupely can run a saved configuration on a schedule and merge automatically against safety rules, with unlimited users and integrations on every plan. Sigmera is a manual pass on a file — it has no scheduler and nothing to watch.

Choose Sigmera if…

You have a CSV in hand and want the duplicates gone before it is imported anywhere.
The file holds personal data you would rather not upload or hand to another processor.
The export came from something that is not a CRM — a survey tool, an event platform, a spreadsheet.
The list needs more than deduplication: phone formats, email casing, split name columns.
You want a fixed, small cost that does not scale with how many records you own.

Choose Dedupely if…

The duplicates are already inside HubSpot, Salesforce, or Pipedrive.
Your duplicates differ in spelling, so exact matching will not find them.
Both copies of a record hold data worth keeping, and you need per-field merge rules.
New duplicates arrive continuously and you want scheduled automatic merging.
You need to deduplicate CRM objects — companies, deals, custom objects — not just rows in a file.
