About Exclaimer & Technical Insights
What this service does and the technologies behind it.
Read the tech stack as text▾
Overview: A modern B2B SaaS stack that pairs a decoupled JAMstack marketing site with AWS-backed product assets, wrapped in multi-channel ad tracking and edge security.
What stands out
- Marketing site appears decoupled from product: Netlify serves the front end while AWS hosts the core application.
- AdRoll and LinkedIn Insight Tag indicate multi-channel paid acquisition aimed at B2B decision-makers.
- Cloudflare and HSTS reveal security and compliance as trust signals for email signature management.
- S3 storage suggests asset-heavy workflows, likely signature images, logos, or downloadable templates.
Technologies exclaimer.com uses
- Netlify — Hosts the marketing site on a modern JAMstack platform, enabling fast, developer-friendly updates.
- Amazon S3 — Stores downloadable assets, email signature images, or static files at scale for global delivery.
- Linkedin Insight Tag — Tracks B2B visitor behavior for LinkedIn ad targeting.
- HSTS — Enforces HTTPS-only access to protect user sessions and data.
- Cloudflare — Provides CDN, DDoS protection, and DNS for global performance.
- AdRoll — Runs retargeting campaigns for display ads, supporting paid acquisition of B2B leads.
- Amazon Web Services — Hosts Exclaimer's cloud application and services on AWS.
How these technologies work together
- Amazon S3 runs on Amazon Web Services — S3 is AWS's native object storage, so Exclaimer's static assets and downloads sit directly on its cloud infrastructure.
- AdRoll works alongside Linkedin Insight Tag — AdRoll retargets display audiences while LinkedIn tag enables B2B ad targeting, supporting multi-channel paid acquisition.
- Amazon S3 integrates with Cloudflare — Cloudflare can cache and shield S3-hosted assets, improving global delivery for signature images or downloadable files.
- Cloudflare works alongside HSTS — Cloudflare can enforce HSTS at the edge, ensuring HTTPS-only access and reinforcing compliance trust for B2B SaaS.
- Amazon S3 works alongside Netlify — Netlify serves the marketing site while S3 stores downloadable or user-generated assets, separating delivery layers.
- Cloudflare overlaps with Netlify — Both provide CDN and edge caching; Netlify already includes a global CDN, so Cloudflare may be layered for DNS/security.

How to fix Exclaimer not working
Exclaimer provides email signature management for Microsoft 365 and Google Workspace. Administrators set a company signature once, and it is added to outgoing emails from the right people. Find your symptom below. Most problems come from a signature rule, a sign-in, a sync delay, or the platform itself. Check the signature rule applies to the mailbox that is sending before you change the signature.
Jump to what you are seeing
Signatures Not Appearing
Emails go out without a signature, or with an old one.
- Check the signature rule applies to the sender's mailbox and the right group.
- Send a test email from that mailbox, and check whether it has the signature.
- Check status.exclaimer.com, and wait for a sync to finish before you change the rule again.
Website Down
The Exclaimer website does not load for you.
- Open the page in a private window and on another network.
- Check status.exclaimer.com for an active incident.
- If only your network is affected, ask IT to check the firewall.
Login Failed
Sign-in is refused.
- If the message says the password is wrong, reset it through the official route and check spam.
- Check you are using the administrator account for your organisation.
- Try a private window to rule out an old session.
Sync Issues
Signatures are not updated in the mailboxes after a change.
- Check the mailbox is licensed and included in the sync.
- Allow time for the change to reach the mailbox, then check again.
- Check status.exclaimer.com, and report the mailbox name and the time if it stays out of date.
Editor Not Loading
The signature editor stays blank, or it will not save.
- Reload in a private window, and try another browser.
- Turn off any extension that may block the editor.
- Check status.exclaimer.com, and copy the signature text somewhere safe before you try again.
Slow Performance
The dashboard or the signature set-up is slow.
- Narrow the view to one group or one signature.
- Try again at a quieter time of day.
- If it is slow for everyone, check status.exclaimer.com.
Still not working?
Contact your organisation's Exclaimer administrator or your IT team first, since they manage the mailboxes and rules. For a platform-wide problem, contact Exclaimer support through the help option in the dashboard or on the Exclaimer website. Have your organisation name, the mailbox or group name, the exact error text, and the time with your time zone. Never send passwords or customers' personal details in a support message. Live incident updates are on status.exclaimer.com.
Most signature problems come from a rule that does not match the mailbox, or from a sync that has not finished, and they usually clear once that is checked. The status page shows live incidents, so you can see whether the problem is on Exclaimer's side.
