Spam filters constitute the principal mechanism for what allows Email service providers henceforth addressed as ESPs to separate unsolicited dangerous spam emails from normal emails. These filters are designed to be extremely strict, so they may at times flag your non-spam emails as spam if there is even a minute mistake in the content.
Spam filters pay special attention to the email’s subject line. Ergo, the best way to avoid such filters is by carefully curating the contents in the subject line of your email. We’ve compiled a list of 200 words you must always avoid while writing the subject line of your email. These words can be more or less categorised into 6 groups;
- Manipulative –which instills urgency, unwanted pressure
- Needy –which creates desperation, overstates claims
- Sleazy –which sounds unsolicitedly pushy
- Cheap –which is too easy to procure
- Far-reaching –which propagates utopian claims
- Shady –which raises questions about legal legitimacy
Manipulative Triggers
Instilling urgency always in the minds of readers is unwarranted by the spam filters. Every email you send cannot be “urgent” because if everything is urgent then essentially urgency loses its meaning and nothing is urgent. Consequently, if the email copy is created well and adds value to their primary line of work, urgency would be automatically created in the minds of the readers. Here’s a list of Manipulative terms to avoid:
