Ideally, a subject line shouldn’t exceed 3-4 words (approx 17-40 characters) to sustain the recipient’s attention and accommodate the preview space. While the length might vary by the type of device and email application, it’s always wise to go by the thumb rule.


Mentioning the prospect’s name in the subject line increases the chances of getting clicked by 50%. Now that if they’re strangers to you, try to refer to something personal and relevant. It might be a recent publication that you found striking) or a common passion that you share with them.

Tips on How to Write a Networking Email Subject Line

Keep it brief and to the point

Since 41.9% of emails are read from mobile devices, long subject lines would be simply a waste of time and effort. On the other hand, lengthy sentences might trigger spam factors. Therefore, a wise way would be to use a subject line checker, so that you stick to the best criteria. It can help avoid spelling mistakes, grammatical errors, and unclear details. You can also get a rough sense of your message concerning readability, engagement, word count, and deliverability.

Schedule it rightly

How can you ensure the chances of opening emails by the leads? Schedule it in the work hours between 9 am to 5 pm. Avoid sending them before holidays or at the end of weeks which might leave the mail unnoticed in the inboxes. Either way, even if the leads wish to respond to you after their private time, chances are they will forget.

Commit to sincerity

If you promise something to your prospects in the email, deliver it. If you try to tweak the motif anyhow, your brand will face the heat. Therefore, you should make your prospects feel the happiness of serving them with some kind of sincerity. Thatb will itself play the game for you.

Explore new formulas every day

While a particular pattern might deliver success for a specific individual, that might not be the case every time. Don’t be formulaic while sending emails. Think the other way- if your prospects are receiving the same emails again and again, it would feel robotic and cold.

Consider the situation

Your networking email subject line and body should concern the current situation of the prospect. Don’t bring something out of the blue. Including factors like place of meeting, the personality of the lead, and things you two have in common would be a unique strategy to get hands on. When the leads will know about your vested efforts, they will also reward it somehow.

Be prompt to connect

As the saying goes, the quicker you take the action, the better you get benefitted. Coming to this context, if you’ve attended any networking event recently, don’t be late to contact your prospect. Connect with them within a day. Otherwise, leads might forget things to some extent, hampering the connection.
