Good... when it works
I've been using this product since December 2024 and it generally works pretty well. The UI/in app navigation takes a little bit of getting used to. The customization options are flexible enough for my use case.
My issue, however, is that about 1/3 of the time all the images break in my signature. There doesn't appear to be any consistent cause that I can identify. So when that happens, I either waste time manually removing the entire signature and typing it out myself, or I just send it as is and it looks quite unprofessional.
Went through all of Support's troubleshooting steps months ago, and have been trying to coordinate a screenshare to no avail. Unfortunate, because it could be a good product and I'm unable to roll it out across my team.
EDIT Sept 11, 2025: Downgrading from 3 stars to 2 stars. I booked a call with their support team to finally get this resolved. I joined the call to see that the employee who was supposed to arrive, didn't. Nor did he communicate at all. Someone else named "Sushma" joined that call, camera off, which was fine. She asked me to wait a few minutes for the other person to join. After about 3-4 minutes, she silently dropped off the call without a word. I waited for another 10 minutes or so before realizing that I was ghosted and leaving. I emailed them about it, and ironically, had the exact same issue in that email too: all images in my signature were broken.
Still waiting on a resolution. Bad experience overall.

Support took my suggestion and implemented it in less than 2 weeks
I had NewOldStamp but it seemingly hadn't made any updates since 2018 when I purchased tier 1... They require upgrade to tier 4 in order to use the M365 integration-- It's still a good deal but I decided to try SyncSignature and compare the two.
The integration with M365 is seamless and easy to assign signatures in bulk. My only issue originally was that it assigns the signature on every email-- even when replying. I asked support about this and now less than two weeks later it's implemented. There is now an option to include the signature in "New Emails", "Reply Emails", and/or "Forward Emails" from within the plugin
Great job, thanks Sunny!

Sep 3, 2025Thank you so much for sharing your honest thoughts. I am sure there are plenty of benefits in choosing SyncSignature lifetime deal over NewOldStamp lifetime deal, this is probably one of them ;)
We loved your suggestion and it was definitely something that a lot of people would've benefitted from- so we had to get that out quickly and we did :)
We are on our way to be the best email signature...

SyncSignature is good, but...
At the time of review there are 2 different signature apps available on AppSumo and I ended up getting both to see which one was best for me and to be honest, both are very good so I've still given SyncSignature 5 stars even though I ultimately didn't keep it.
It ultimately came down to some specific design preferences and the look and feel of the site that influenced my decision on which to keep. In this case I while I found SyncSignature to be very good, I wanted additional design options on how to display social icons and the phone/web etc icons which the other one did and this didn't as far as I could find.
It does give some good control over the layout and design of your signature however the templates were not quite what I was looking for and you can only edit them so far.
I feel like as this product matures it will only get better so if you're looking for a signature app, it's worth checking out before the deal ends.

Sep 1, 2025Hi Dave,
Thanks for your honest thoughts. I really appreciate that. I definitely think that there are certain aspects of the platform which still need a bit of work that we are actively working on. Both deals have their own benefits, for ex. SyncSignature would be ideally more suitable for companies and agencies with high volume of signatures. As an individual, you do get a pretty decent email...
