Tips

1. Dynamic parts in email senders can be replaced with asterisk sign (*). For instance:
   • Uber often send emails from "uber@uber.com" or "no-reply@uber.com". Rather than managing separate filters for each unique address, we can use *uber.com to capture all emails from Uber.
   • Slack sends each login code from a unique address, and the only consistent part of the address is the email domain, "slack.com". To filter emails from Slack, we have to use *slack.com as the sender address
2. Dynamic parts of subjects can be replaced with asterisk sign (*). For instance:
   • In my experience, Uber only sends 3 types of emails: account related, trip receipts, and promotional. Account related emails' subjects usually structured as "___ Uber account ___", therefore, subject line would be *Uber account*. Similar system can be observed for trip receipts, and subject line would be *trip with Uber.
   • Hetzner sends monthly invoices with invoice number in the subject line. Since we cannot know the invoice number before hand, or write a condition for each possible number, we have to use asterisk for where invoice number would be. In my experience, the subject line would be Hetzner Online GmbH - Invoice *.
   • We receive emails with sigle use login codes, and many companies contain those in subject line, which makes every email subject unique. For example, Slack's login codes follow "Slack confirmation code: ###-###" structure, therefore, we shouold use "Slack confirmation code*" to catch those emails.
