26 Internal Email Subject Lines (Examples and Best Practices) - Page 2

Tone:

Straightforward, Neutral

Email Subject Line Content:

This one’s sharp, to the point, and useful when you need to move something forward. “Any update on this?” works best when there’s a shared context.

Don’t use it cold. The recipient should know what “this” refers to, like a proposal, a bug fix, or next steps.

“Any update on this?” subject line can sound blunt, so soften the body of the email slightly. Works great if your last message already explained everything clearly.

Type:

Client Projects, Freelance, Business

Tone:

Empathetic, Soft, Clarifying

Email Subject Line Content:

I like this one because it’s honest and easygoing. Sometimes priorities shift, and you don’t want to be the person pushing something that’s no longer relevant.

“Just checking in” is familiar, while “is this still a priority?” shows respect for their workload. You’re not assuming urgency; you’re asking for clarity.

Use this with long-term projects, invoices, or client conversations that stalled. It also helps you clean your task list if you need to know whether to keep following up or pause.

This is one of my go-to subject lines when a relationship matters and you want to leave the door open either way.
