Prospects often hesitate to open emails, fearing a lengthy commitment. By adding an estimated read time (e.g., '3-minute read') to your pre-header, you manage expectations, remove friction, and make it easier for them to engage, which boosts open rates.

A great cold email is judged on three criteria: 1) Packaging (subject line and preview text), 2) Body (personalization, problem/solution language, and social proof), and 3) Style (personal flair, formatting, and length). Mastering all three is key to getting replies.

The single biggest lever for cold email success isn't the copy or sending strategy—it's the offer. Truly compelling, high-value propositions, such as fundraising for a fast-growing startup or an M&A inquiry, will inherently generate high response rates.

Sales director Florin Tertulia uses cheeky, playful subject lines like "Ronald's beef. Isn't with us" to create a "scroll stopper." This tactic is designed to break the pattern of standard corporate emails, sparking curiosity and standing out in a crowded C-level inbox.

Prospects have minimal attention spans. To capture their interest, marketing copy in emails or social posts must be 75 words or less and contained in a single paragraph. Reserve longer, more detailed content (100-150 words) for your existing customer base, as they are already invested and more willing to read.

Adding a deeply personal postscript (P.S.) to cold emails, such as referencing the recipient's favorite whiskey, demonstrates genuine research and builds rapport. This simple tactic humanizes the outreach and can dramatically increase the likelihood of getting a response from a busy executive.

To break through the noise, Astronomer used a subject line that simultaneously qualified the recipient and created intrigue. This direct, almost challenging, approach proved highly effective in capturing the attention of their specific target audience—Airflow users—and drove successful email campaigns.

Readers often hesitate to open content, fearing a significant time commitment. By explicitly stating the 'read time' (e.g., 'a two-minute read') in email pre-headers or social posts, you remove this uncertainty. This small addition manages expectations, making people more likely to open the content immediately or save it for a known-duration break later.

When stakeholders demand cramming too many product updates into one email, position yourself as the expert. Explain the science of audience attention—that users won't read past a certain point or absorb more than a few items. This shifts the conversation from personal opinion to data-backed strategy.
