Mistake 1: Leading with your company name. Nobody cares about your company until they care about the problem you solve. Lead with the problem. Introduce the company later, if at all. In a first touch, the company name matters less than the relevance of the message.
Mistake 2: Writing too long. If your email has more than six sentences, it won't get read on a phone. Most email is read on mobile. Design for mobile: short paragraphs, one idea per sentence, total length under 100 words.
Mistake 3: Using "I" more than "you." Count the pronouns in your email. If "I" and "we" outnumber "you" and "your," the email is about the wrong person. Flip it. Make every sentence about the buyer's situation, problem, or desired outcome.
Mistake 4: Asking for a meeting in the first email. A meeting is a big ask from a stranger. A question is a small ask. Start small. "Is this a priority right now?" If they say yes, then you've earned the right to suggest a conversation. The first email's job is to start a dialogue, not book a call.
Mistake 5: Sending one email and giving up. Most replies come on the second or third touch, not the first. Build a three-email sequence: initial outreach, a value-add follow-up (share a relevant insight or resource), and a final check-in. Space them three to five business days apart. The sequence does the persistence so you don't have to.
