Finally I've seen an interesting email coming from one of widely known airline tickets aggregators.
The email had a lot of interesting information for casual flyers:
- airport lifehacks
- tips on how to spend couple free hours around most popular airports
Of course it won't be new to a frequent flyers e.g. business travelers, but for me as a casual traveler that was a bunch of useful and never known before tricks. Fabulous!
But even that great email had a flaw. I've tried to unsubscribe from their digest just to check their unsubscription flow. Everything went fine except the fact I didn't find a way to re-subscribe. It means you're likely to not see some new great emails from them.
