Frequently Asked Questions

What colours are used for Halloween envelopes?
Halloween envelopes focus on the classic seasonal palette: black, orange, deep green and dark purple. Black and orange are the strongest colour combination for Halloween visual impact at the letterbox. Deep purple and forest green add gothic character for premium invitations and spooky event mailings.

What are Halloween envelopes used for?
Halloween envelopes are used for party invitations, seasonal greeting cards, direct mail promotions and event announcements. They are popular with craft sellers, event planners, retailers running seasonal promotions and anyone sending physical Halloween-themed correspondence. C6 is the most common size for invitations; DL for longer promotional inserts and season greetings.

Are halloween envelopes compatible with Royal Mail?
Yes — standard sizes (C6, DL, C5) qualify as large letter within Royal Mail's weight and thickness limits. Always weigh a complete, sealed envelope before posting at volume — cards with multiple inserts may push the weight above the large letter threshold.

The courier let us down, but Jess and Kelly were hugely helpful and did everything they could to resolve it. They even arranged to specially stock products I order regularly to make future orders smoother. Great quality, good value and excellent customer service, with the phone answered on the first ring!
