The SMS and WhatsApp platform built for fundraisers.
Automated supporter journeys. Live JustGiving and Enthuse integration. Milestone-triggered messages that reach the right person, at the right moment.
The problem
Your supporters deserve better than a broadcast email.
You've got 200 London Marathon runners on JustGiving. Some have raised nothing. Some are at 80% of their target. Right now, they're all getting the same newsletter.
The right message, sent at the right moment, can restart a stalled fundraiser, retain a first-time donor, and recover a lapsed direct debit.
Thread Messaging is built on one principle: every supporter is on their own journey.
How it works
A supporter journey that responds to what people actually do.
Thread Messaging can connect to your CRM and giving platforms. This means every message can be triggered by a real event.
Why Thread
The tools exist. The sector expertise doesn't. Until now.
The capability that sets our platform apart
Thread Messaging can connect to your CRM, giving platforms and donation provider via API. This means messages can be triggered automatically by real actions and milestones - targets hit, page not set up, updated information.
You can also personalise messages to each participant using AI - without a member of staff touching it. This is live, working and deployed today. No other UK charity messaging provider is currently offering the range of integration and stewardships that Thread does.
Pricing
Three tiers. One platform. No long-term contract.

Frequently Asked Questions
Do we need consent before sending SMS or WhatsApp messages?
The new soft opt-in laws outlined in Data (Use and Access) Act 2025, means that you don’t need explicit opt-in for sending SMS or WhatsApp messages provided you follow PECR and your own charities privacy policy allows it. Though there are certain conditions:
- Existing Supporter: You must have obtained the phone number directly from the individual.
- Sale or Negotiation: The number was collected during the sign up of a marketing or fundraising product / event etc. .
- Similar Products/Services: The marketing message is about your own similar products or services.
- Opt-Out: The first message you send must have an opportunity to opt-out and subsequent messages make it easy to unsubscribe too.
If you don’t use the soft opt-in laws then you’ll require explicit opt-in consent for marketing or fundraising messages by SMS or WhatsApp. A single, clearly worded checkbox on your registration form or donation page is all you need to start collecting this properly.
What is the JustGiving integration setup fee?
£995 + VAT. This covers API configuration, journey build, template approval, and a guided walkthrough. It reflects approximately one day of skilled configuration work and typically pays for itself within a single campaign.
Can we use Thread just for WhatsApp, or just SMS?
Yes — you can use either or both channels. Thread Messaging is built for both, but you're not required to use both. Many charities start with SMS and add WhatsApp once they have opt-in consent from their list.
What happens if we run out of credits?
Auto top-up is built into all tiers. When your balance drops below £10, the card on file is automatically charged so your messages never fail mid-campaign. You can set a monthly spend cap if preferred.
Do we need technical expertise to set up Thread?
No. Pre-built templates and a guided setup mean most charities on Stitch and Weave are sending within hours. The Thread team is on-hand to help and we have a range of training videos, hands-on support and tools to help you get the most from the platform.
Is there a minimum contract length?
No. All tiers are available monthly with no long-term commitment. Annual billing saves two months' cost but there is no penalty for staying monthly.
Every great supporter relationship starts with a well-timed message.
