A client starts judging the delivery before the first full image opens. They notice the link, the cover, the logo, the page speed, the wording, and whether the whole thing feels like it was made for them or just generated and sent.
Use a cover that feels like a doorway
The cover photo should invite the client in. It does not always need to be the most dramatic shot. Sometimes the best cover is the one that feels calm, emotional, and easy to read behind the title.
Name the stack like a keepsake
"Amina & Tunde Wedding" feels better than "Client delivery 03". A title can be practical and still have some care in it.
Let the first action be obvious
Clients should not have to hunt. View photos, favourite, download, pay, or contact you - the main action should be clear within a few seconds.
Do not over-explain
Premium does not mean more text. It usually means less text, better placed. Give the client just enough instruction to move with confidence.
