Using Unicode Symbols in Email Subject Lines

I recently tested using a Unicode symbol in an email subject line to see if it made any difference to the open rate %.

The subject lines I tested:


✈ Save 20% on your Next Flights

Save 20% on your Next Flights

The results after 3 days were...

✈ Save 20% on your Next Flights - 19.00% open rate
Save 20% on your Next Flights - 17.85% open rate

So a 1.15% increase in opens, not game changing but putting something new in your subject line is likely to 
surprise your audience and increase opens. Use with care, if used to frequently  people will soon get used to seeing them on your emails.
