Don't switch CRMs. Add the part that follows up.
Bloomerang is a respected donor CRM — but retention isn't a database problem, it's a follow-up problem. Tongba is the AI layer that drafts and sends your re-engagement emails, with you approving each one. It runs alongside Bloomerang, any CRM, or no CRM at all.

Layers on top of the tools you already use
Retention isn't a database problem. It's a follow-up problem — and no CRM has ever written the email for you.
Dollars are up, but the number of donors has fallen four years running. A better CRM tells you who slipped away in more detail. It still doesn't bring them back. The work that actually reactivates a donor is the work no one has time for.

Tongba
The case against ripping out your foundation.
Three things every fundraiser learns the hard way.
A CRM knows who lapsed. It won't write the email.
Bloomerang can tell you 47 donors haven't given in 13 months. Then it waits for you to open a blank page 47 times. The database isn't the bottleneck — the follow-up is.
Switching CRMs is expensive, political — and won't fix retention.
Migrating donor data, retraining the board, re-importing history: months of work. And at the end, you still don't have anyone writing the re-engagement emails. The leak stays open.
Add the missing layer instead of ripping out the foundation.
Tongba is the AI outreach layer that sits on top of whatever you already use. Your records stay put. The work that never got done finally gets done.
Keep your CRM. Add the layer. Send the emails.
Watch how Tongba sits on top of Bloomerang — your records never move.

Hi Maria — two years ago, your $1,240 gift funded 40 meals.
This week a family near you needs that same help.
Would you bring them back to the table with a gift today?
We've missed you, Maria
Keep Bloomerang exactly as it is
Export the donors who lapsed — no migration, no new system of record.
Two honest ways to start.
Tongba is CRM-agnostic. Bring one, or bring none.
Already on Bloomerang?
Keep it. Add Tongba as the AI reactivation layer — export a CSV, and Tongba drafts, queues, sends, and reports. No migration, no risk, nothing to retrain the board on.
Works alongside your CRM
Don't have a CRM yet?
Skip the heavy setup. Tongba is a lighter, AI-first way to hold your donor list and actually do the outreach — no system-of-record project before you can send a single email.
From $39.99/mo
1,204 rows · 38 duplicates merged · 47 lapsed flagged · CRM unchanged
One CSV. No migration. Nothing locked in.
Export the lapsed segment from Salesforce, Bloomerang, or DonorPerfect — or upload a plain spreadsheet. Tongba dedupes it, computes who's lapsed, and starts drafting. Your system of record never moves, and you can stop anytime.
- Email, name, last gift amount and date — that's all the export needs
- Automatic dedupe and lapse detection on import
- Your system of record stays exactly where it is
- Cancel the export habit anytime — nothing is locked in
Tongba vs. a donor CRM on its own.
Different jobs. Tongba does the outreach; a CRM keeps the records. Most orgs want both.
| Capability | Tongba | Donor CRM alone |
|---|---|---|
| AI-drafts personalized donor emails | yes | no |
| Lapsed-donor reactivation, ready to run | yes | partial partial |
| Approval-before-send inbox | yes | no |
| Works without a CRM | yes | no |
| Stores full donor records + giving history | partial partial | yes |
| Deep reporting & board dashboards | partial partial | yes |
| % of donations taken | 0% 0% | 0% 0% |
| Setup time before first email | ~10 min ~10 min | ? ? |
Not a knock on any CRM — this contrasts Tongba's focus (AI outreach + approval) with what a records-and-reporting CRM does on its own. “?” means it varies by vendor and plan; check each vendor's site for current details.
A team that loves its CRM but never had time to follow up reaches every lapsed donor in an afternoon — without migrating a single record.

Bloomerang alternative — FAQ
Is Tongba a replacement for Bloomerang?
It can be either. If you don't have a CRM (or want something lighter), Tongba works as your donor list + AI outreach. If you already use Bloomerang, keep it — Tongba runs alongside it as the AI reactivation layer, importing a CSV.
Does Tongba integrate with Bloomerang?
Today, via CSV import from Bloomerang (and Salesforce, DonorPerfect, Givebutter, or a spreadsheet). Two-way sync is on our roadmap. You never have to migrate to try it.
Why choose Tongba over a standalone CRM for outreach?
A CRM stores your data; Tongba does the work. It drafts personalized re-engagement emails, queues them for your one-click approval, sends, and tracks replies — the busywork a CRM leaves to you.
How much does Tongba cost?
Plans start at $39.99/mo with a 14-day free trial and monthly AI-credit allotments. No per-contact fees, and we never take a percentage of donations.
