Choosing the right method

Match the service to the communication

Different campaigns need different levels of formality, reach, cost and proof. Letter Drops work best where a formal appearance matters but named addressing is not required.

Which service suits formal communication without named addressing? +

Letter Drop A letter-style format delivered to all households in a defined area. It carries the visual authority of formal correspondence without requiring named address data.

Which service offers the broadest cost-effective household reach? +

Door Drop A leaflet or printed item delivered to all households in a target area. Best for awareness campaigns where a promotional format is appropriate and cost efficiency matters.

Which service suits named or personalised communications? +

Direct Mail For communications that need individual addressing. Best when you have a data list or need to personalise by name, property type or account reference.

Which service suits tracked, sensitive or time-critical campaigns? +

+POST Letterbox's tracked delivery service, built for communications where formal delivery assurance, GPS confirmation or address-level proof of delivery is essential.

Which service suits public consultation or planning notification? +

Letter Drop or +POST Planning notifications are often best served by a letter-style format for formality. Where a tracked audit trail is required by the planning authority, +POST tracked delivery provides that assurance.

Which service suits infrastructure or utility project communication? +

Letter Drop The letter format is widely used by utility companies and infrastructure project teams to notify households ahead of works. It carries more perceived authority than a standard door drop leaflet.
