A visitor enters their postcode, sees their MP’s name, constituency, party, and email, and gets a campaign letter they can edit before sending. Clicking the button opens the letter in their own email client via `mailto:` — the email is sent by the visitor, not your site, so you carry no responsibility for moderating outgoing mail. Features: * Postcode to MP lookup with no API key required. * Multiple campaigns, each a separate entry with its own shortcode `[wtym_write_to_mp slug="your-campaign"]`. * Editable letter templates with placeholders for MP details and supporter-entered fields. * Configurable visitor fields (first name, last name, postal address) per campaign, with optional required validation. * Friendly handling of invalid postcodes, vacant seats, and MPs with no public email. * Self-contained, responsive styling that inherits your theme fonts. Placeholders: * From the MP lookup: `{mp_name}`, `{constituency}`, `{party}`. * From the supporter (the fields you enable): `{first_name}`, `{last_name}`, `{ address}`. ### External services This plugin looks up MP details from two public services, called server-side only when a visitor submits a postcode: * postcodes.io (https://postcodes.io) — converts a postcode to a constituency. Privacy: https://postcodes.io/about * UK Parliament Members API (https://members-api.parliament.uk) — returns the MP’s name, party, and contact email. Terms: https://www.parliament.uk No personal data is stored by this plugin; the letter is sent from the visitor’s own email client. ## Screenshots [⌊The postcode lookup form embedded on a campaign page.⌉⌊The postcode lookup form embedded on a campaign page.⌉[ The postcode lookup form embedded on a campaign page.

Upload the plugin and activate it. 2. Go to Write to Your MP and add a campaign. Set the intro, subject, letter body, and supporter fields. 3. Publish the campaign and copy its shortcode. 4. Paste the shortcode into a page (in Elementor use the Shortcode widget, not the HTML widget). ## FAQ ### Does this send email from my server? No. It builds a `mailto:` link that opens the visitor’s own email client with the recipient, subject, and body filled in. The visitor reviews and sends it themselves. ### Do I need an API key? No. Both upstream services are free and require no key. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Japeto Labs – Write to Your MP” is open source software.
