The short version

  • Each has a real cost: 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); OpenGrants coverage of private foundations is thinner and less curated than Candid or Instrumentl, so a prospect list built solely from OpenGrants will miss foundations that never post public opportunity notices.
  • They diverge on capability: Constant Contact covers Email marketing, OpenGrants covers Grant search.
  • 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.

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)

OpenGrants

  • Coverage of private foundations is thinner and less curated than Candid or Instrumentl, so a prospect list built solely from OpenGrants will miss foundations that never post public opportunity notices.
  • The index leans on public opportunity feeds, which means it is strongest on government funding and weakest on the relationship-driven private philanthropy that most nonprofits actually rely on.
  • Matching is keyword driven rather than fit-scored, so users receive alerts for opportunities they are ineligible for and must qualify each one by hand.
  • The consultant marketplace is a directory with variable quality rather than a vetted panel, so buyers carry the risk of choosing a weak grant writer themselves.
  • It is a US-focused index, offering little to organisations seeking UK, EU or Canadian funding.

Answered from the vendors’ own pages

OpenGrants: How much does it cost?

$9 a month or $99 a year after a seven day trial, with a free tier of core search retained.

OpenGrants: Why is it so much cheaper than Candid?

Because it indexes public and semi-public opportunity feeds with automation rather than employing researchers to code foundation records from tax filings. You trade depth of private foundation intelligence for price.

OpenGrants: Does it cover private foundations?

Partially. It is strongest on federal and state programmes. For systematic private foundation research, Candid remains the reference source.

OpenGrants: Is the consultant marketplace vetted?

It is a directory, not a vetted panel. Check references and past awards yourself.
