The short version

  • Only Constant Contact has a free tier, so it costs nothing to try first.
  • 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); Sumac pricing is not published at all, so a small organisation cannot compare Sumac against per contact priced competitors without committing to a sales process.
  • They diverge on capability: Constant Contact covers Email marketing, Sumac covers Donor and gift management.
  • 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)

Sumac

  • Pricing is not published at all, so a small organisation cannot compare Sumac against per contact priced competitors without committing to a sales process.
  • The interface reflects the product's age, and staff arriving from consumer grade software find navigation and data entry slower than in newer CRMs.
  • Holding client case notes and donor records in one database makes permission design a compliance obligation, and a misconfigured role can expose confidential client material to fundraising staff.
  • The integration catalogue is small, so payment, email and accounting connections outside the listed few mean manual export or paid custom work.
  • Modular licensing means the price rises in visible steps as programmes expand, and organisations frequently discover the module they need most was not in the original quote.

Answered from the vendors’ own pages

Sumac: Is Sumac the same product as Societ?

The vendor has been moving its products under the Societ brand, so you may see both names for the same platform during a sales cycle.

Sumac: Can it handle client case management?

Yes, that is its clearest differentiator among donor CRMs. It is a licensed module, not part of the base product.

Sumac: Is pricing published?

No. It is quoted by module and organisation size, which makes like for like comparison harder than with published per contact products.

Sumac: Does it work for US charities?

Yes, though the vendor is Canadian and its receipting and support conventions are strongest for Canadian organisations.
