We use this for our small business and it seems to be working well — and it is completely free. I echo a couple of other reviews which highlight that you have to log out and back in to the signature manager to make directory changes work. It's not that clear from the instructions, but this is the workflow > — Update the data in Directory and save them — Wait at minimum 10 minutes. There is a lag between saving the data and Google making them visible by API to the app. — Log out and back in to the app. — Publish the signature — Reload your Gmail I got that workflow by contacting support, and the reply was really fast (like 2 mins) and helpful from Martin Šůs. We're using a bespoke HTML signature, and mapping the variables was simple. The variable name don't quite match Google Workspace's names, but it's pretty easy to work out with a bit of tweaking. Perfect bit of software, esp for free.

Okay, because this is the ONLY free signature manager for google workspace, and it actually does work. That makes it better than every other one, so let's elevate it. A few people mention the developer by name in reviews which made me think the reviews were fake, but I opened a help ticket, and the dev did indeed respond. I will recount some gotchas to save some people some trouble. If you're gonna use any dynamic fields, make sure those fields are populated for EVERY user. If you make changes in the user directory, they don't work right away, and you have to log out of the signature manager and log back in to get fields to populate. The field flags don't match up with the field labels exactly, like {{ PERSONAL_EMAIL }} matches the user's account email, which is probably their Work Email, but {{ COMPANY_PHONE }} is their Work Phone in the directory. Not a lot of consistency in the flag names mapping to the field names, but it's workable. If you use the built-in email templates and include any links, like logo links or social media, the links that get published will be different, tracking user click-throughs via sendgrid for some reason that is of no benefit to you. This is the only reason I'm removing a star. I can live with the gotchas and I appreciate the free tool very much. Use a custom HTML template to avoid the clickjacking.

Such a great tool and its all free! very simple to use, the templates are just want we needed, and create profesional looking signatures for all users in the matter of mins. I am so glad we used this tool for our company, easy to apply different signatures to different people and lots of choice with custom fields. Had one small issue when deploying, and like others have also said in reviews, had very quick response on support by email, also from Martin Sus, and he was so helpful, and it was a very quick fix to my problem. Thank you so much for making such a great tool so easy to use and also free, and also providing such a great level of support.

Not good at all. Dynamic tags must be outdated, things like job titles will not populate. the create a signature from raw HTML seems completely broken, it will not properly load. I wasted a few hours on this , I wish I could get them back.

We love this tool for our company, it's been very useful. Had a small issue at one point, but it was actually my fault for not quite understanding the error message that was shown on the screen. Submitted a support ticket via the Revolgy website, and got pretty much instant support from Martin Šůs, jumped on a Google Meet and shared screens, and resolved in seconds. He also taught me how to use the Custom Fields, which work great! Thank you so much, wouldn't expect this level of support especially for a FREE app!

I have successfully published signatures and this tool has been really helpful. Our marketing team love it. Faced some challenges here and there but the support was great and we resolved everything with this guy Martin Šůs. Great support. I hope it continues being improved especially loading speeds. But overall this tool is great!

This app is fantastic! Support team was super responsive and helped me figure out where I'd gone wrong (user error, app works great). Now our non-profit can have custom email signatures and its great!
