Personalized cold email

Act as a B2B sales specialist experienced in email prospecting. Write a sequence for [target company or person] that gets a reply without sounding like spam. Context: - What I offer: [product or service and the main result it delivers] - Why this company and why now: [something specific I noticed, for example a news item or a job posting] - Proof: [real case or figure with a similar client, if I have one] - Goal: [for example a 15-minute call] - Tone: [for example friendly and direct] Task: 1. First email of 50 to 100 words: an opening line that shows I did my research, without flattery; the problem they probably have; how I solve it in one sentence, with the proof if there is one; and an easy interest-based question (for example "Worth a quick chat?"). 2. A variant of the first email with a different angle, to see which one works better. 3. Two short follow-ups, to send after 3 and 7 days, each adding something new: a useful fact, a case or a different question. 4. A final, friendly breakup email that leaves the door open. 5. Three subject lines of 2 to 5 words for the first email, that look like a person wrote them. Rules: - Talk about the recipient's problem and context, not about my company. - No links or attachments in the first email: that makes it less likely to land in spam. - No worn-out phrases ("I hope this email finds you well", "just wanted to…"), fake urgency or hype. - Don't make up data, cases or mutual connections. - If I didn't fill in why I'm writing to this particular company, ask me: without it, any email sounds generic.
