The number of charities that have failed to comply with suppression requests made through the Fundraising Preference Service has fallen by 37 per cent in the past six months.
The Fundraising Regulator said the fall highlighted the fact that fundraising standards were improving.
Members of the public can use the FPS to stop communication from charities they do not wish to hear from. Six months ago, the Fundraising Regulator began naming charities that did not respond to requests to cease communications.
In its monthly online newsletter, published today, the regulator said that since it began producing a public list of those who did not respond to FPS suppression requests, the number of charities on the list had fallen by 37 per cent over the past six months to 37 charities.
No household-name charities feature on the current list.
A spokeswoman for the regulator told Third Sector: "It is encouraging to see more and more charities accessing and acting on FPS requests. There are several reasons for this, including the decision to name charities not acting on their requests.
"More importantly, this highlights the improving standard of fundraising communications across the sector, which helps to build public trust and confidence in fundraising."
The regulator reduced the amount of time charities had to respond to FPS requests from 28 days to 21 days in March, to bring the rules in line with the Data Protection Act 2018.
