Send Letters Online

Send Letters Online is a UK-based letter posting service for individuals, businesses and public sector organisations who need printed mail sent from the UK. It accepts typed or uploaded letters and posts them via Royal Mail, including domestic and international options.

Users compose or upload a PDF in the browser, add recipient details, and the service prints, folds, envelopes and despatches from a UK facility. Features listed on the site include same-day despatch for orders before 2:30pm UK time, proof of postage on eligible orders, colour and double-sided printing, tracked and signed services, and a REST API for automated transactional mail and CSV mail merge for bulk sends.

The service removes the need for a local printer, stamps or a Post Office visit and provides audit trails and posting confirmation. Customers receive printed letters posted from the UK, with options for tracked, signed or special delivery and support for statutory and compliance correspondence.
