Feedback we have received from MPs of all parties proves our campaigns are heard: MPs tell us they appreciate hearing their constituents' views and that they make decision on how to vote and what action to take with their constituents' messages in mind.

For MPs who agree with our campaign aims, receiving dozens of messages from constituents as part of a coordinated campaign helps strengthen their resolve. It gives them proof they can point to that their constituents agree with their position. It helps them make the case theat their MP colleagues should also go along with them.

For MPs who don't agree with your aims, receiving dozens of messages from constituents may make them think twice. It will certainly push the issue up their agenda and mean they cannot claim their constituents do not care about the issue.

We know MPs talk to eachother. They are work colleagues as well as political allies and opponents. They talk in the corridors, and waiting in line to vote, and in the bars and tearooms, and over Whatsapp. It is extremely helpful to any campaign for MPs to be telling eachother how many messages they are receiving about it, to hear that other MPs have also been contacted about the campaign, to feel that the campaign is big and supported nationwide.
