1. Warm up your message. Start and end messages by making a personal connection. "Dear soandso..." and sign off with a bit of a flirtation... "Thinking of you" or "Passionately Yours..."
2. Try text tips
It can be hard to express your thoughts and feelings in writing - so take from the writing experts, quotes, or check out some romantic websites like:
St. Valentine's Love poems
Daily Love Poems
3. Sending romantic e-cards are also great all year round.
4. Crank up the heat
Increase anticipation with a few provocative suggestions. While you may not want to give all the hot details in e-mail, the mere mention of an event or an article of clothing can do the job.
5. Emoticons can be flirty so use them wisely ;)
6. Watch the email address you're sending to and respect that person's email - E-mail sent to company e-mail addresses may be monitored. So be discreet or stick with a personal e-mail account whenever you can.
Happy Emailing :)
