Email signature was very siWe’ve been using Exclaimer primarily for managing email signatures across Microsoft 365, and overall it has been a very positive experience.

The user interface is clean and easy to navigate. Creating and managing signatures is straightforward, even without much prior experience. The layout makes sense, and updates can be done quickly without confusion.

Integration with Microsoft 365 was very simple and smooth. The setup process was easy to follow, and the tool integrated seamlessly with Outlook and other M365 apps. Once configured, signatures were applied consistently across users and devices without any manual effort.

In terms of performance, Exclaimer has been very reliable. It works well with Microsoft 365 and does not impact email delivery or user experience. Signatures are applied correctly every time, and we haven’t noticed any performance issues.

Pricing is reasonable and offers good value for money. Considering the centralized management, consistent branding, and time saved for IT and users, the return on investment is good.

Support is okay overall, but it’s somewhat limited. Support is mainly available via email due to the subscription plan. The responses are helpful, but having faster or real-time support options would improve the experience.

Exclaimer doesn’t heavily focus on AI or intelligent features, but for its core purpose—email signature management—it performs extremely well and does exactly what it promises.

Overall Experience

Exclaimer is a solid, reliable solution with easy Microsoft 365 integration, good performance, and fair pricing. While support options could be improved, it’s a dependable product that delivers strong value for organizations using M365.mple Review collected by and hosted on G2.com.

Personally I don't have any negatives about exclaimer. Overall its good product. Review collected by and hosted on G2.com.

I like that Exclaimer keeps our email signatures consistent across very different teams, from the field reps who email doctors and chemists daily to the export team corresponding with overseas partners. The central control is what makes it indispensable to my work. I can roll out branding updates, banners, and the right disclaimers and certifications from one central console rather than chasing each department, so every email leaving the company stays professional and on-brand without my having to check inboxes. I rely on it constantly, and its integration with Microsoft 365 means updates roll out quietly in the background, with nobody needing a tutorial or a nudge to comply. It belongs to that rare category of tool that smooths the workflow so well that most colleagues never notice it is there. What saves me the most time day-to-day is template updates deploying automatically through the Microsoft 365 integration, so when I change a signature element or swap a banner, it applies to everyone's outgoing mail at once without staff updating anything or me chasing each department. When we refreshed our corporate branding and needed a new logo and product range banner on every signature, I pushed the change out from one console in a single pass, which spared me coordinating each department and prevented the mismatched, half-updated signatures a manual rollout would almost certainly have produced. The initial setup took a few days, but we didn't encounter any major problems, so I have to admit it was actually quite simple. Review collected by and hosted on G2.com.

{"My main reservation is the editor, which feels rather restrictive when it comes to layout choices.","Getting to grips with how the rules actually behave took longer than I expected.","During that learning curve a few incorrect signatures slipped out.","Putting those right added an extra layer of work and caused a measure of confusion across teams in the early days.","The incorrect signatures mostly came down to rule precedence, where overlapping rules for different departments meant some users matched the wrong one and received a signature meant for another team.","There is a lack of clearer visual feedback in the rule editor showing exactly which rule wins for a given user before the changes go live."} Review collected by and hosted on G2.com.

What I love most is the upgraded analytic dashboard that just launched recently. It has changed how our marketing team justifies the cost of email signature campaigns internally. Before that dashboard existed, the value of a campaign was something everyone assumed rather than something anyone could demonstrate, and now that it's there, the budget conversation has become considerably easier. I can show click through rates on a campaign, compare performance between different banner designs, and track engagement trends over time, which gives the team real data to bring to quarterly reviews instead of anecdotal evidence. The most impactful metric for me is the click through rate, because now we can show how many quality clicks are coming from the campaign in the email, so we can keep using the same campaign for future sales and marketing. Our campaign budget is really low now because it doesn't cost much to display the marketing on email. There were times when we overspent on social media campaigns and it was really costly but the results weren't really good, and after using email marketing with the banner on email, it basically costs nothing or much less, so we have more budget for other forms of campaign. I also like that the Google Workspace setup through the marketplace has improved over the past year, and it's now straightforward enough that most administrators get through it without adding support.

I think things that need to be improved is the competitive pressure from alternative like code two and since sign since. They have become a real conversation at renewal time. Both have closed the features gap meaningfully in 2026 and offer a lower price for midsized organization without the tier complexity that Exclaimer carries. The CSS editor limitation forces designers to work within the WYSIWYG editor rather than editing CSS directly. This is a recurring frustration that competitive tools have addressed and Exclaimer has not. Setup time requires planning the whole structure across our brands and multiple departments before touching the platform. Review collected by and hosted on G2.com.

I love Exclaimer's UI life's preview, which lets me see the disclaimer text update across a sample signature before publishing changes. This gives me confidence that our team's email won't break before reaching everyone's inbox. The integration with our email platform has been smooth, allowing disclaimer updates to apply automatically without manually touching each department's individual template. Exclaimer's performance is consistent, with changes propagating quickly across the organization without noticeable delay. Review collected by and hosted on G2.com.

I dislike that there isn't a built-in approval workflow for template changes. Also, AI and intelligent features don't really fit our use case, even though I can see potential value in more advanced enforcement for certain legal requirements. Review collected by and hosted on G2.com.

I find Exclaimer extremely helpful for managing individuals' signatures across multiple companies on a single platform, which simplifies a previously cumbersome task. I especially like the interchangeable banners, as they help address some of our marketing shortfalls by keeping customers informed about our latest developments. The ability to change data and logos in one step is another feature I really appreciate. Exclaimer's global management capabilities are also a standout for us since it doesn't just manage our tenants within our country but globally. The setup was seamless as long as we had the right information. Review collected by and hosted on G2.com.

Exclaimer must be able to handle multiple MS Exchange accounts. Currently, Exclaimer can be set for a single MS tenant. We have global companies on MS Exchange and incorporating them into Exclaimer would be advantageous. Review collected by and hosted on G2.com.

Exclaimer has saved us a considerable amount of time by removing the need to manually monitor and correct email signatures. Changes are easy to implement and can be rolled out across the organisation quickly, ensuring consistency and reducing administration—a reliable and user-friendly platform.

Set-Up was straightforward and the Exclaimer team were very helpful Review collected by and hosted on G2.com.

As ever, we would always want things to be cheaper, but ultimately we would always pay for a quality product that doesn't give us additional problems Review collected by and hosted on G2.com.

Our organization can instantaneously handle corporate email signatures throughout all the departments from one on the platform central cloud dashboard. The visual drag and drop designer eases the process of creating brand-conformant layouts without the need of advanced HTML knowledge. Review collected by and hosted on G2.com.

The template designer is very constrained and often bends a lot of intricate layouts when he has to produce signatures for older email clients. Non-standard web typography support is non-existent which makes it very difficult to implement custom font styles. The analytics dashboard offers very little tracking information and lacks of granular click through data for each marketing banner. Review collected by and hosted on G2.com.

I like the automatic process that allows Exclaimer to query directory fields and use that data to personalize signatures automatically. It's especially helpful when a client staff member gets promoted, as their new title reflects in outgoing emails as soon as the directory is updated. This way, important details like URLs, phone extensions, and office locations are updated without manual intervention. For clients with high staff turnover or frequent role changes, this automated accuracy is invaluable. Review collected by and hosted on G2.com.

Copying signature templates between brands and branches is more difficult than it should be. For clients managing multiple brands under one organization, the inability to easily duplicate a template from one brand setup and adapt it for another adds unnecessary repetitive work. Some clients have found this frustrating enough to start evaluating alternatives, specifically because the multi-brand management experience does not match the quality of their single brand expertise.

The centralized dashboard allows you to have full control of corporate email branding throughout the organization. The drag and drop template builder makes it easy to create professional looking signatures. We were able to make the unified company banners and legal disclaimers available to all employees in minutes. It integrates with our email provider, so that all messages appear to be flawless on mobile devices. Review collected by and hosted on G2.com.

The admin interface is extremely slow and freezes frequently during the peak working hours. When a user profile is updated, it can sometimes not be synced, without the display of any helpful error messages. The billing structure seems like a scam for a smaller company that is going through a growth spurt. Review collected by and hosted on G2.com.

I really like Exclaimer's user customization structure. It makes our business much happier after switching to it because our template locks down legal and branding elements to keep everything on-brand, while still allowing each staff member to fill in personal details like pronouns, direct mobile numbers, and working hours through a self-service portal. This balance between central control and personal flexibility has stopped any pushback from staff who were worried about losing control over how their email signatures look. No one has complained since we went live because they still feel that their signature represents them, just within a company-controlled structure. I also appreciate how the template standardizes email signatures to protect our brand image while allowing some personal touches to make signatures feel more personal.

The WYSIWYG editor has a CSS limitation. It shows up when our designer tries to recreate our brand signature exactly. Some spacing, font rendering, and element positions that look perfect in design files don't translate accurately through the editor. The workaround involves uploading a prebuilt HTML file, but that requires our designer to be involved every time there's a structural change, rather than a marketing person being able to do it themselves. Proper CSS editor access would remove that dependency. Review collected by and hosted on G2.com.
