Earl of Sandwich’s birthday bonus appears to be a birthday gift sent through its Royal Rewards / email club , but the public sources I found do not specify the exact timing window for delivery. One current source says members get a “special welcome & birthday gift,” and another roundup says the birthday treat is a free cookie or brownie.

What it means

  • The reward is tied to signing up for Earl of Sandwich’s rewards program.
  • The birthday treat listed publicly is a free cookie or brownie.
  • I could not verify an official “sent on your birthday” vs. “sent a few days before” schedule from the available public pages.

Practical expectation

  • In practice, birthday rewards from restaurant loyalty programs are often emailed around the birthday period, but the exact day can vary by program. That said, I can’t confirm that timing for Earl of Sandwich from the sources available here.
  • If you already signed up, check your inbox and promotions/spam folder around your birthday month.

TL;DR

Earl of Sandwich does offer a birthday bonus, but the public info I found confirms the reward , not the exact send date. It’s listed as a birthday gift through Royal Rewards, with a free cookie or brownie mentioned in a birthday freebies roundup.
