1. The Decision Maker – 

Subject line – Can I Help {{prospect company name}} With Higher Sales?

This subject line insists prospects take quick decisions. This kind of subject line clearly states the purpose of reaching out to the prospect.

When writing a B2B sales email, it’s tempting to write an open-ended sentence. But writing a focused sentence is far more effective and would give an insight to the prospect. Instead of saying “What if (prospect) could do x?”, craft something like: “(Prospect), having the ability to do x will improve your business in the following ways…” By drilling down on who you are writing to and what the benefit is for them, you make it about them and their needs rather than how excellent your product or service is.

The benefit that you’re providing should target a specific aspect of the prospect’s business, for example, shipping efficiency or brand growth. While closing on the subject, it is important to have a clear idea of “What does my product/service/idea do for this customer?” It can be really helpful to get feedback from customers about what their biggest pain points are while using the product, so you can craft a message that addresses those pains.

2. Call To Action –

Subject line – Hey {{Name}}, Check-Out This High Converting XYZ Playbook

The subject line will be the first thing people see when they open their mailbox, so it needs to be enticing enough to make them want to click the link. Utilize this opportunity to grab their attention by using a clear and descriptive subject line that makes them want to click.
