How we tested the best letterbox flowers:
There were quite a few different things we looked at when weighing up the pros and cons of each of these letterbox flower delivery services. For starters, we assessed how easy the site and process was to navigate, and looked at the number and variety of individual arrangements each had available. As well as next day delivery, we also only picked services that offered specific named day delivery — as clearly the date is crucial if you're sending anniversary or birthday flowers.
Next we scoured the reviews — and in some cases, relied on our own personal experiences — to suss out the actual quality of the fresh flowers. How many days did they stay last? Were they sparse or bountiful once bloomed? Did they come with flower food? What about tips and tricks for arranging? These were all key points for helping us determine how happy customers were overall.
With all this information, we’re pretty confident that we’ve covered all bases, and brought only the very best letterbox flower delivery services to your attention.

How to arrange the best letterbox flowers?
First off, unbox your letterbox flowers, and fill two-thirds of your chosen jug or vase with clean water. As well as any that have wilted, remove leaves that'll end up sitting below the water line of your chosen jug or vase. Then trim around an inch or so off the end of each stem — making sure you cut at a diagonal angle so they are able to absorb as much water as possible.
Chances are your delivery will come with some advice for arranging them like a pro — but if not, give this beginner-friendly approach a go: start with any lush foliage at the base, then add secondary flowers and fillers like smaller blooms and stocks, and finish up in the centre with your show-stoppers and focal flowers.
How long do letterbox flowers last after delivery — and how can you keep them fresh for longer?
Most high-quality letterbox flowers will come with at least a seven day freshness guarantee from their delivery date — but with proper care and maintenance, it's totally possible for your beautiful flowers to live even longer.
As well as changing out the water and re-trimming the stems every couple of days, try to display your bouquet in a cool and shaded area that isn't in direct sunlight. Adding flower food to the water can also really help extend the life of your flowers — but if your letterbox package didn't come with any, you can drizzle in a few drops of bleach instead.
