The from name and preview text, the email before the email
The short answer
Before the subject line, a prospect sees who it is from and a snippet of preview text. Those decide the open as much as the subject does. Use a real person's name, not a company or a no-reply, and treat the first line as preview text that earns the open rather than wasting it on a greeting. Small details, real difference.
Everyone obsesses over the subject line and ignores the two things sitting right next to it. The from name and the preview snippet are read in the same glance, and together they often decide the open before the subject gets a vote.

The from name is read first
In the inbox, the sender name usually sits before or above the subject, and it answers the reader's first question: do I know or trust this. A real person's name reads as a person writing to them. A company name or a no-reply reads as marketing, and marketing from a stranger gets deleted.
For cold outreach, send from a real human. It is the single easiest from-line improvement, and most senders get it wrong.
Preview text is a second subject line
Most inboxes show a snippet of the email's start next to the subject. That preview is prime space, and the common mistake is to waste it on Hi [name], I hope this finds you well, which tells the reader nothing and signals a template. The first line should carry relevance, because it is doing the work of a second subject line.
What works in the from name
Keep it human and recognisable.
- A real first and last name, a person, not a brand.
- Consistency, the same sender the prospect will see again in follow-ups.
- No no-reply, which kills replies and trust at once.
- Optionally the company, but the person leads.
What works in the preview
Because the preview is drawn from the opening line, write the opening line to be seen at a glance. Lead with something specific and relevant, the same first line that would earn the read inside the email. Do not open with a greeting or boilerplate that a preview will surface as noise.
The glance is the whole battle
From name, subject line and preview are consumed together in under a second, and that glance decides whether the email is opened or deleted. Optimising only the subject, while sending from a company address and opening with a hollow greeting, leaves two thirds of the decision on the table.
Get all three right and more emails get opened, which is the necessary condition for everything the subject line and the body are trying to do.
