7 Quick Tips to Write Event Email Subject Lines That Increase Open Rates
The best email subject lines for event promotion or follow-up ignite enthusiasm in recipients. They feel ready to check out what's in store for them. To create such email subject lines, keep in mind the following points: 

1. The subject line's tone of voice should depend on the age and demographics of your audience. Industry professionals will like a business casual tone, while a younger group will be attracted by an informal tone along with emojis. 
2. Avoid spam words at all costs from the subject lines. These words make exaggerated claims and promises. Some notable examples are 100% free, cash bonus, free gift, and free membership.  Gmail filters emails with spam words and they go to the spam folder of the recipient.  
3. The more personalized an event email subject line is, the more it is likely to be opened. Lines with the names of the recipient or their location are always appealing.  
4. A/B test a wide variety of subject event email subject lines. These can be question-based, teaser lines, those with a pinch of humor, and countdown subject lines.  
5. Add social proof in your lines to increase the open rates. An example is #1 Software on G2!  Come attend our event. 
6. If possible, make the email come from an actual professional in your company rather than software or your company name.  
7. Select the right email marketing tool to make scheduling and delivering emails effortless. Eventcombo's Email Marketing Engine feature in the all-in-one event management platform lets you craft custom emails and enrich them with multimedia of choice.
