Share aInbox and both of you get extra summaries every day.
Your unique code is included at the bottom of every summary email you receive from aInbox.
Tell them to add ref:YOURCODE anywhere in the subject line when they forward their first email to aInbox.
Once they send their first summary, you both get bonus summaries — automatically, no extra steps.
What you get
Both you and your friend receive +25 extra summaries per day for each successful referral.
Your referral code is auto-generated the first time you use aInbox. Just check any summary reply you've received.
Each friend can only be referred once, and you can't refer yourself.
