Reactivate from the tools you already use
The donors you already have are walking out the back door — because no one had time to follow up.
Dollars are up, but the number of donors has fallen four years running. Winning a lapsed donor back is far cheaper than finding a new one — yet it's the work that quietly never gets done.

Reactivation by hand vs. with Tongba.
By hand
- Export, dedupe, and eyeball the list for who lapsed
- Stare at a blank page for each donor
- Write maybe 10 before the day gets away from you
- Forget to follow up; the other 200 go cold
- No idea who opened or replied
With Tongba
- Drop the CSV — lapsed donors flagged automatically
- A personal draft waiting for every single donor
- Approve a batch in minutes, in your voice
- Every donor reached, none left behind
- Opens, replies, and dollars-back tracked live
A two-person team reaches every lapsed donor on their list in an afternoon — instead of the ten they'd manage by hand.

Lapsed donor reactivation — FAQ
What is lapsed donor reactivation?
Reactivation is re-engaging donors who gave before but have stopped — typically anyone whose last gift was 13+ months ago. It's the cheapest growth a non-profit has: about 66% of prior donors who are reached give again, versus 24% of brand-new donors (M+R Benchmarks 2026).
Do I need a CRM to use Tongba for reactivation?
No. Tongba works from a CSV exported from any CRM — Salesforce, Bloomerang, DonorPerfect, Givebutter — or a plain spreadsheet. It runs alongside your existing tools; there's nothing to rip out or migrate.
Does Tongba send emails automatically without me?
Never. Every AI-drafted email lands in your approval inbox first. You read each one, approve or skip in a click, and only the ones you approve are sent.
How does it personalize each email?
Tongba reads each donor's real history — last gift amount, date, and what it funded — and drafts a short, specific note in your organization's voice. No mail-merge tokens; a genuine four-sentence message per person.
What counts as a 'lapsed' donor?
You decide the window. The default is a last gift more than 13 months ago (so you catch donors who skipped a full giving cycle), but you can set 6, 12, 18, or 24 months per segment.
How long does it take to set up?
About 10 minutes: drop in your CSV, pick the Lapsed Donor Reactivation workflow, and review the first batch of drafts. Every plan starts with a 14-day free trial, no card required.
