Better Email Subject Lines, Written by Humans

Each word in a subject line means something. They contribute to the overall cost of your email, and once they are written, you will have to rely on them more than the body while the reader decides to open it. That’s why it’s expensive to rely on a topic to guess the subject line.

Once you send us a completed email, we will give you a list of alternatives based on your approach instead of 50 odd variations of the same sentence. Testing a comma vs. a semicolon illustrates nothing at any list size you are likely to have.

Why No-AI Email Subject Lines Need a Human Voice

Well written subject lines depend upon the article that they introduce. Most fail that obvious step. The best subject lines are usually a line or phrase that is in the fourth paragraph or beyond. That is where the author has stopped explaining and finally states what he or she has been talking about.

  • Written after the email exists, never before it.
  • Front-loaded for a phone that truncates around forty characters.
  • Variants that differ in approach rather than in wording.

Where AI falls down on email subject lines

Your suspect e-mail subject lines have first ordered colon construction, next ordering question structures, and finally ordering numbered list structures. This is because most machine text generation models implement a three step procedure. Send those to your competitors automated campaign list, and every line in that inbox looks similar to the same email.

How We Write No-AI Email Subject Lines Around the Reader

We group the options we send by angle: direct angle, curiosity angle, etc. Each angle is sent with the preheader belonging to it, because the judgment of whether a subject line works or not is not in isolation from its preheader - we test them together.

How an email subject line gets written here

  1. Read the finished email and mark the strongest sentence in it.
  2. Write options in three groups: direct, curious and problem-first.
  3. Check each one truncated at forty characters on a phone.
  4. Pair every subject line with a preheader that extends it.

Using No-AI Email Subject Lines Across Your Email Funnel

Rewards and lines in different areas of a program are designed to filter content in distinct ways. Cold email, for example, needs communication that appears to have been sent colleague to colleague. A newsletter will need to offer a guarantee that an issue will be published. Transactional will be most concerned with the actual words a reader will look for in eight months. When we write, we do it according to the slot. We don’t hand one bank over.

  • Subject lines grouped by angle with the reasoning noted.
  • Character counts and a truncation preview for each line.
  • A matching preheader written for every option.
  • Notes on which pairs are worth testing against each other.
  • Words flagged that commonly trip promotional filters.

What people commission email subject lines for

  • Testing a program with flat open rates.
  • Retitling a backlog of scheduled campaigns.
  • Cold sequences where the subject decides everything.
  • Rewriting automated emails nobody opens anymore.

What email subject lines cost

One rate, whatever the format: $10 per 100 words. You are paying for the writer’s time and judgement, so the price scales with the words rather than with a package tier.

Line breaks can be misleading. Two lines with only one comma separating them would show no difference no matter how big your list is. Take the “direct” version and the “curious” version and see which one does better. Keep the winner.

We would rather not, and we will say so. A stated promise in the topic line of an email often times leads the reader to believe there will be more detail in the email. This will mean the loss of this opportunity and also the next opportunity. If the email is not yet written, include the offer and the outline at the very least.

Sounds like me on a good week

I have my own newsletter publication most weeks. I send the hard ones to my colleagues. No one on my distribution list has noticed the change. Someone responded this week saying that they think that was my best one yet. It was a bit of a hard blow, cutting it loose.

Shortest cold email i’ve ever sent

Sixty-two words including the signature. Our response rate went from something I would rather not admit to approximately one in nine. I requested three variants, and the shortest of the three won by a landslide.

Short enough that people will answer

First drafts, each ninety words. No “I hope this finds you well” openers, please. I liked that the first lines you wrote referenced a specific detail about each client’s business. It meant I actually had to provide a well-researched prospect list to begin the project. Well worth it.
