"Good free signature option"
I really liked that htmlSig offers a free signature for personal use. A downside is that there's no option to include my Tableau Public profile link among the social icons. It's not a must-have, but I use this signature when contacting recruiters, and having that link would add some flair to my profile. Previously, I used a manually created signature that often got misaligned in recipients' inboxes. HtmlSig solved that problem for me.

"Simplifies creating e-signatures"
Setting up is a breeze, and it makes e-signatures effortless to use. I'd definitely recommend it. There are many icons available to showcase your social media profiles, like Facebook, Snapchat, Twitter, WhatsApp, and more, which is great for promoting your online presence right in your signature. Having all signatures in one dashboard is convenient, and the basic trial is reasonably priced. The website offers plenty of helpful guidance from start to finish. I know many users and have only heard positive feedback. I can't think of any downsides; it's been smooth so far, so I have no complaints. It's easy to set up and looks professional, and the social media icons are a handy way to spread the word about our platforms.

"No coding needed for email signatures"
The tool is straightforward to use, has a smart interface, and offers a highly customizable price. However, the design options are limited, and occasionally the formatting breaks in the generated email signature.

"Terrible customer support experience"
Initially, I found the tool user-friendly, but I'm now terminating my subscription due to abysmal customer support and a missing refund. I downgraded my plan on the renewal day and have been emailing Raquel on their support team for over three months, but she hasn't resolved it. I still haven't received my refund, and she only says she'll check with billing. It seems their policy is to auto-renew without warning and refuse refunds. I've been a customer for years without problems until now. The system incorrectly counts my signatures, prompting me to upgrade even though many were deleted long ago, and my basic account is maxed at 50.

"Attractive email signatures made simple"
What I appreciate most about htmlsig is the combination of templates and form filling. You simply enter your details and it generates a polished email signature for you. A minor gripe: copying the signature requires opening a new tab, which is a slight inconvenience. Overall, it saves me from building signatures manually in Gmail.
