Wren vs. HubSpot's signature generator.

HubSpot's email signature generator is a genuinely good free tool for a solo consultant. Fill in the form, get HTML, paste it once, move on with your afternoon. It's not really trying to be a team product — it's a top-of-funnel capture for HubSpot's marketing suite, which is fine. Where the wheels come off is the moment you have a small team, or you want the banner under everyone's signature to actually change when your Q4 launch ships.

Wren
HubSpot generator
What it is
A team product: shared design system, hosted assets, install tracking, live-swappable banner. Also a free single-user tier.
A free lead-gen tool. Fill in a form, get HTML, paste it into your mail client. Designed as a top-of-funnel entry point to HubSpot's marketing suite.
Templates
20 designer Looks with a coherent grammar, live-edited in a studio with an accurate Gmail / Outlook / Apple Mail preview.
6 basic templates. Fine for a solo consultant; visibly generic once several teammates run the same one.
Banner behaviour
Hosted image URL is stable. Change the image and every teammate's signature updates on the next send — no re-paste.
Banner URL is hard-coded into the exported HTML. Changing the banner means every teammate re-generates and re-pastes.
Photos and logos
Hosted on Wren's own infrastructure. You upload once, we optimise it, and it renders crisply in every mail client.
You provide a public image URL yourself. If it's on Dropbox or Google Drive with restricted access, it renders as a broken image for recipients.
Team features
Owner dashboard, install tracking, one-click resend of install links, per-teammate personalisation with a locked brand shell.
None. It's a one-off generator; there's no concept of a team or a central admin.
Analytics
Per-banner click counts across the team, so you can see whether the launch banner actually did anything.
None baked in. You'd wire your own UTMs and track in your analytics tool.
Price
Free for 1 person. $99/mo flat for a team up to 50, $199/mo up to 100.
Free forever. There's no paid tier because the product is a lead capture, not a business.
Best for
Any team of 5+, or a solo user who wants a great-looking signature and to run a banner campaign that actually stays current.
A single freelancer or consultant who wants a serviceable signature in 5 minutes and is happy with a HubSpot marketing email or two in exchange.

The three moments HubSpot's generator stops being enough.

The second hire

Now you have two signatures to keep in sync. In practice, they drift within a month — different photos, different phone formatting, one has a title update the other doesn't.

The first launch banner

You add a banner, everyone pastes. Two weeks later the launch is over. Getting the banner back off — or swapping to the next campaign — means every teammate re-does the process. Most never do.

The broken photo

Whoever built the signature used a Google Drive link for their headshot. Six months later they tidy their Drive; every recipient starts seeing a red X where their face used to be.

Design one for free — no HubSpot signup needed.

Open the studio, pick a Look, paste into Gmail or Outlook. Two minutes end to end.
