Skip the witty email(s) and just get right to the fvucking point and on the very first email invite them to drink with you.
This is a great way for you to stand out and grab their attention, and more importantly, you'll maximize your chances of meeting as many women as efficiently as possible.
Don't risk wasting your time on attention wh0res who just want to be e-validated with back-and-forth emails and textathons.
When you email a chick to drink with you, she's limited in the way that she can react: she can say "yes" or "no", or, she can ignore you; or, she can use an excuse ("I don't know you well enough"; "I don't date guys without talking to them first" blah blah blah).
If she says "no" or ignores you, or uses excuses, then you simply go ghost and wait a few weeks and invite her out again.
And, I invite you to consider that "getting a number" is not only completely unnecessary, but I wouldn't even consider it an accomplishment.
These days, I NEVER ask for a phone number--this includes online dating AND dating in the so-called "real world."
Chicks give their phone number out like candy on Halloween. I see absolutely no value in getting a girl's phone number. They check their emails just as much as (if not more than) voicemail/texts.
If I want to make sure she's showing up to drink with me, I'll simply email her the day of: "Hey just finishing up a project. See you tonight at The Rusty Pelican at 7." If they don't respond to that email, then I won't show.
Take the power AWAY from her by never asking for the number. Allow HER give it to YOU--without your ever even asking for it.
A phone number often just slows things down. There's no need for it. I like to invite them to drink with me & then go ghost until I meet them in person. I don't want to be texting and emailing them before the face-to-face meeting.
Just be sure invite them to drink with you at a specific time, at a specific place, on a specific day--on the very first email--and you'll see that the ones who say "yes" and are truly interested in meeting you will almost always volunteer their phone number without your ever even having to ask for it.
