Why it matters

For every £1 an eligible donor gives, your charity can claim an extra 25p from HMRC. Claiming Gift Aid on text donations in the past wasn't possible because charities couldn't tie every declaration back to the original donation without detailed reporting from mobile networks. Cymba solved that.

Solves the audit problem

Charities have never struggled to convince donors to Gift Aid a text donation; the barrier was always proving it. Without a way to tie a declaration back to the exact gift it belonged to, HMRC's audit requirement was impossible to satisfy.


  • Ties every Gift Aid declaration back to the original donation
  • Meets HMRC's audit requirement with clear, traceable reporting
  • Removes the reporting gap that blocked Gift Aid on text donations for years

After the ask, not during it

Asking someone to fill in a form in the middle of giving breaks the moment and kills momentum. Cymba waits until the donation itself is already confirmed before the Gift Aid conversation even starts.


  • A secure link is sent by text once the donation is confirmed
  • A quick tap completes the declaration and sets communication preferences
  • No mid-campaign forms to interrupt the moment of giving

Consent is handled at the same time

A Gift Aid declaration and a consent update don't need two separate asks. The same short journey captures both, so your team isn't chasing preferences in a second conversation at a later stage.


  • Communication preferences captured alongside the declaration
  • Keeps donor data GDPR-compliant with a clear consent trail
  • One less admin task competing for your team's time

Secure by design

A Gift Aid link carries real financial and personal details, so it needs to be treated that way. Every link Cymba sends is unique, time-limited, and tied to a single donation, never a generic form anyone could stumble onto.


  • A unique link per donation, so every declaration ties to the right gift
  • Links expire after a set number of days, reducing fraud risk
  • Real-time Royal Mail address validation catches errors before they cost you

Mobile Gift Aid collections help Poppy donations bloom

When COVID-19 severely disrupted the 2020 Poppy Appeal, the Royal British Legion needed to adapt its fundraising fast.


Cymba's mobile Gift Aid collection let the charity capture eligible declarations by text at exactly the point donors were already giving, recovering income that would otherwise have gone unclaimed during a uniquely difficult year for in-person collection.
