Staring at a blank card on someone's birthday is one of those small but real frustrations — you care about them, but "Happy Birthday, hope your day is great!" feels like it could've been written for anyone. Sendly writes a message shaped around the actual person: their name, their age if you want it included, and the relationship you share, so the words feel like they came from you and not a greeting card aisle.

Use this one →They say age is just a number. That number is concerning, but happy birthday anyway.
Use this one →Keep it short and specific rather than warm and generic — a brief, true detail ("I always appreciate how you handle X at work") reads as more sincere from an acquaintance than an enthusiastic "Hope your day is amazing!!" would. Two or three honest sentences are enough.
Yes for most adults, and it often makes the message feel more intentional rather than copy-pasted. The exception is anyone sensitive about a specific number — if you're unsure, naming the milestone ("a big one this year") works without stating the figure.
Name the milestone directly instead of writing around it — "Welcome to your thirties" lands better than a generic message that happens to be sent on a 30th birthday. Milestone birthdays are also where a little reflection on the years behind them fits naturally, more than it would on an ordinary birthday.
Three to five sentences is enough for almost anyone. Length doesn't signal how much you care — specificity does. A short message with one real detail beats a long one that could apply to anybody.
