Questions

Everything you wanted to ask

Quick answers about the tools in this category — what they cost, what they need and how they work.

Still have a question? We usually reply within one working day.

Which parts of an email do these tools work on?
The two that sit either side of your message. A subject line generator for the words that decide whether anyone opens the mail, and a signature generator for the block under your name holding your role and contact details.

Can I try more than one subject line?
Run the generator as many times as you like and keep the wording that fits. Feed it the point of the email and the audience you are writing to, then compare the options side by side in a document. Nothing limits how often you use it.

What makes a subject line worth opening?
Something specific. A line that names the thing inside the email beats a vague greeting every time. Keep it short so phones do not cut it off, skip the shouty capitals, and make sure the message delivers what the line promised.

Can the signature generator handle a job title and links?
Yes. Give it your name, role, company and the ways people should reach you, and it builds a tidy block to paste into your mail client. Export it as HTML if your client accepts formatting, or as plain text if it does not.

Is any of this paid?
No. Both tools are free with no cost and no trial, and there is no account or sign up in the way. They run in the browser as guest tools, so you can use one once and never come back if that is all you needed.

Do I need a design background for the signature?
Not at all. You fill in the details and the layout is handled for you. If your company has a house style, edit the exported text afterwards. Everything runs on phones, tablets and desktops with nothing to install first.

Does signing in change anything?
Signing in is optional and only saves your history. That helps when you are testing subject lines across a campaign and want last week's wording back. The tools behave the same either way, so skip it when you are in a hurry.
