It makes the prospect feel you are speaking directly to them.
Like you are asking for their opinion. (Which you can actually do too - more on that in a sec).
Even if you're not actually wanting people to uae number data reply you can still use questions.
It gets people to engage with your emails more.
Examples include;
SUBJECT: Does my butt look big in this email?
NOTES:
SUBJECT: How can I help you?
NOTES:
Inside I asked them to fill out a simple survey on how best I could help them.
I used the results to create my next offer.
SUBJECT: Is it a bird? Is it a plane? No it's...
NOTES:
Inside I spoke about a product which helped you get fast search engine rankings and was "super" like superman.
Notice how this one used multiple questions, humor and curiosity.
Triple threat!
Being Specific and Using Statistics
Use Statistics in Your Subject LinesWhich subject line is best?
A: "Weird Method Leads to More Revenue..."
B: "New Method Leads to 157% More Revenue..."
C: "This Method Leads to $1982.43 More Revenue..."
Yes.
You're right - C is the winner.
Because it is the most specific one.
As humans we like to know unknown stuff. We like all the gaps to be filled in.
The more detail you can give (as long as it's relevant and interesting) in a short subject line, the more people are likely to open it.
This is half the battle.
To really get the most from your email marketing campaigns you should also be...
Harnessing the Power of Help
Asking for Help in Your EmailsThere is something inside us as human beings - we want to help others.
Too many business owners make the mistake of thinking they should always be preaching to their subscribers.
Like they are shouting from a pulpit and the subscribers should just be good audience members.
BUT:-
"The real power of email marketing comes when you start building this into a two-way interaction."
Yes you can provide your list with great value, content and offers.
But they can also help you out too.
Whether it's asking for feedback, getting ideas from them, getting them to vote on something or just asking them to take a look at a new article or web page you have -
Don't be afraid to tap into the power of your email list to do this.
You might be surprised by the response.
This also has the added benefit that your inboxing rate and deliverability will improve because email providers like Gmail will see that people are responding to your messages.
In fact, I sometimes run interaction campaigns exactly like this for this very purpose.
