Cold Email vs. LinkedIn DMs: Which Is Better?
You can send more than 500 or 2000 emails. However, you must learn how to do it efficiently, without getting flagged by Google.
Here’s a breakdown to help you decide what’s best for your goals.
Cold Email
Here’s why cold email is great outreach channel:
Cold emails are ideal for scalable outreach.
You can send personalized messages to hundreds of prospects and follow deliverability best practices.
Cold emails give you room for longer messages, structured formatting, links, and attachments.
Space for longer messages makes it suitable for B2B outreach where you need to clearly explain your value proposition.
LinkedIn DMs
There are several reasons various businesses prefer LinkedIn to send personalized messages. Take a look:
On the other hand, LinkedIn DMs are more personal.
Since you're reaching out through a social platform, the recipient sees your name, photo, title, and mutual connections.
This can immediately build a level of trust.
LinkedIn is great for starting one-on-one conversations and building rapport.
So Which One is Better?
While both have their pros and cons, here are some reasons why cold-emails are better than LinkedIn DM:
LinkedIn outreach doesn’t scale as easily.
Without automation (and with LinkedIn's strict stance on automation), it’s hard to reach more than a few dozen people a day.
Cold emailing allows for bulk messaging while still maintaining personalization if you use the right tool.
