Your subject line: a checklist
Your subject line is the hong kong phone number list first line of defense when it comes to getting customers to open your email. It's the first thing they'll see, so it reigns supreme in importance. Here's what you need to ask yourself when you're crafting your subject line:
Is it compelling?
You want your subject line to be interesting enough to stand out from all the other emails in the customer's inbox.
Does it contain spammy words?
If you're using phrases like “mega sale!” or “save loads of cash” in your subject line, you're more or less asking spam filters to dump your email into the trash folder. Avoid being over-stuffed - over-the-top language may not get past the latest spam filters, but it will get customers to open your newsletters.

Do you use “!”, “$” or other symbols?
Keep your punctuation to a minimum when crafting your subject line. Exclamation points, dollar signs, ellipses and other symbols will raise a red flag to spam filters. If you have to use a dash or colon, do so, but try to avoid any other type of punctuation.
Is it in all caps?
An all-caps subject line is akin to yelling at a client and usually tips over spam filters. Never design an all-caps subject line.
Is it too long?
Keep your subject lines to 50 characters or less. Most email clients truncate messages with more than that just to make sure your customers see your message, so keep your subject line within this limit.
