The short version

  • Only Constant Contact has a free tier, so it costs nothing to try first.
  • Each has a real cost: Candid grant records derive largely from Form 990 filings, which are published with a lag, so the database describes what a funder did up to eighteen months ago rather than what it intends to fund now.; Constant Contact core plan started at $9.99 per month and Plus plan at $45 per month, both scaling by contact list size rather than a flat rate (Internet Archive capture, 2022)
  • They diverge on capability: Candid covers Foundation Directory, Constant Contact covers Email marketing.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Candid

  • Grant records derive largely from Form 990 filings, which are published with a lag, so the database describes what a funder did up to eighteen months ago rather than what it intends to fund now.
  • Foundation Directory is a research database, not a pipeline tool: there is no proposal tracking, deadline management or task assignment, so most teams pay for a grants tracker alongside it.
  • Monthly pricing is high relative to the budget of a small nonprofit, and the same database is available free in person through partner libraries in the Funding Information Network, which makes the subscription hard to justify for occasional research.
  • Coverage is US-centric and built on the US tax filing system, so it is of limited use to organisations seeking funding from UK, EU or Commonwealth foundations.
  • Many funders do not accept unsolicited proposals at all, and the database cannot reliably tell you which, so prospect lists built from it still require manual qualification before outreach.

Constant Contact

  • Core plan started at $9.99 per month and Plus plan at $45 per month, both scaling by contact list size rather than a flat rate (Internet Archive capture, 2022)

Answered from the vendors’ own pages

Candid: Is Candid the same as GuideStar?

GuideStar is now part of Candid, merged with Foundation Center in 2019. GuideStar nonprofit profiles continue under the Candid brand.

Candid: Can I use Foundation Directory for free?

Yes, in person. Hundreds of partner libraries and nonprofit resource centres in the Funding Information Network provide free access, which is a genuine alternative to a subscription for occasional research.

Candid: How current is the grant data?

It is drawn largely from Form 990 filings and lags real time by roughly a year to eighteen months. Treat it as evidence of past funding behaviour, not current priorities.

Candid: Does Candid help outside the United States?

Only marginally. The data model is built on US tax filings and US registered organisations.
