Can I face problems setting up email signature to my email client due to its character limits?
Some email clients have a character limit for signatures (e. g. Gmail at 10,000). All our pre-designed templates take this into account and will not exceed this limit. If you were to design a custom template, we use some techniques to help you reduce the size of the signature, like removing redundant spaces and styles.

What happens if I change email client?
Your signature is set on a per-client basis, meaning you will have to insert your signature again into your new email client.
Are the number of email signatures I need based on the amount of users we have
companies have general email addresses such as info@company.com, sales@company.com, customercare@company.com. Many companies find it valuable to include their email signature with these email addresses. In this case, you would base the amount of email signatures you need on the amount of email addresses you have.
Does AdSigner work completely on the client-side, without requiring changes to the mail server?
Yes, the signatures are inserted client-side only. Unlike other email signature generators, AdSigner doesn’t read, send or receive the content of your emails. The contents of your emails are protected and secure at all times and don’t leave your environment. Our servers are located in Frankfurt, Germany and Amsterdam, Netherlands.
Is it possible to have multiple signatures per user?
Yes, a user can have as many signatures as needed assigned to them. This could be a signature for internal use, and one for external use for example. The user would toggle between different email signatures in their email client (Outlook, Gmail, etc.) when composing an email.
My email signature looks messy when someone replies or forwards my email?
The reason why this happens?
When your email signature is sent to someone, it looks professional as you intend it to look, because the email is in reading mode. Moreover, AdSigner tests all your email signature in around 80 different email clients to ensure the display of professional email signature design.
As soon as the recipient of your email presses the reply button, their email client converts the email into its own HTML, RTF or Plain Text code and does with it whatever it likes.
The person replying to your email and their email client, now have control over your email signature design layout. When you receive an email back from this person, it could have images removed from it, it may be converted to plain text or it might just be messy. There is no workaround for this, it’s just how email client’s work.
Furthermore, users have the ability to turn off images and change individual user settings that change how their email client receives and send emails in HTML, RTF and plain text formats.
Conclusion
To sum up, yes email signatures may never be perfect but AdSigner has found the best way to ensure your email signature looks just right, effectively dealing with extremely outdated technologies (Outlook 2007, ahem), tables and inline CSS, the Word rendering engine and so many email clients, different devices and screens.
If anybody says they can create a perfect email signature, that will look exactly the same every time it’s sent, received and forward, they are either misleading you or don’t have a sufficient experience in the nish field of email signature as we do.
If you don’t have professional experience in creating email signatures on a daily basis, like we do, you might underestimate how much time and energy goes into creating professionally coded and tested email signature designs that hold up against a lot of these issues.
We are happy to bring new light to the segment of email signature, ensuring we provide you with the best practices in the field of smart professional email signatures and help you grow your business.

Troubleshooting
Why do my images look blurry?
There are many reasons why your images could look blurry.
If you’re using a display with high pixel density (for example MacOS with Retina display), the image resolution in your templates might be too low. Contact us via support chat if you need help increasing the image resolution.
If your images look crisp when composing an email, but sometimes appear blurry in replies or forwarded messages, it means that your recipient’s email client views your images in a lower resolution and compresses them before replying.
Why does my signature appear as an attachment?
Images in your AdSigner should never be sent as an attachment, as this disables your analytics and pollutes your inbox. If this is the case, try inserting the signature again by following the instructions correctly. Note that some email clients will send images as an attachment if you attempted to modify the signature inside your email client’s editor.
Why does the banner in my signature revert to an old banner after sending an email?
When using Gmail or similar browser based email client, you might notice some banners reverting to an old recently changed banner after sending email, especially when you keep the same tab open for multiple hours or days. This happens because browsers do not know the banner in your signature has changed and will keep using the locally cached banner image.
To fix this, simply refresh your web page.
This does not affect how your recipients see your signature.
Campaigns
How do campaigns work?
In AdSigner, campaigns are scheduled displays of banner content that automatically appear in email signatures-without requiring users to manually update anything in their email clients.
You can assign a campaign to specific user groups, such as departments or locations, or let it apply to all signatures across your organization by default. If a new signature is created within a targeted group, it will automatically adopt the active campaign banner according to the schedule you’ve set.
Campaigns are prioritized by creation date, meaning the most recently created campaign takes precedence if more than one is active for the same group.
Additionally, your campaign performance can be tracked in Analytics, allowing you to compare click-through rates and visibility across different campaigns.
📊 Learn more about how campaigns work and how to schedule them: How Campaigns Work
How many campaigns can I have?
With AdSigner, you can create and pre-schedule multiple campaigns to run at the same time across different signature groups-such as departments, office locations, different brands, or teams. This allows you to deliver relevant messaging while keeping everything organized under one system.
Campaigns are prioritized based on their creation date. If two campaigns are scheduled for the same group and time period, the newest campaign will override the older one.
Once a campaign ends, the next one in the queue will automatically go live, based on your scheduling-ensuring a seamless transition without manual updates.

What are the qualities of a successful email signature ad campaign?
A successful email signature banner campaign is built on three key elements:
1. Relevant and Clear Content Unlike traditional digital ads, banners in email signatures are part of personal communication. Since recipients recognize and trust the sender, a concise and relevant message within the banner naturally draws attention. Clear messaging that aligns with your organizational goals enhances both visibility and credibility.
2. Thoughtful Banner Design Visual consistency with your brand is essential. A well-designed banner not only reinforces your visual identity but also guides the recipient’s attention to key information. Use design elements that support readability and reflect your organization’s tone.

3. Clear Call-to-Action (CTA) A banner with a clear and accessible CTA button helps the recipient quickly understand the purpose of the message. Well-placed CTAs enhance user interaction and contribute to better engagement over time.

What is the difference between traditional email marketing and AdSigner's email signature banner campaigns?
Traditional email marketing typically involves sending mass promotional emails to contact lists-often including purchased leads or segmented customer databases. These campaigns are frequently flagged by spam filters, reducing their visibility and engagement rates.
In contrast, AdSigner’s email signature banner campaigns are integrated into regular, one-to-one email communication. Each email sent by your team includes a branded signature with a visual banner that’s relevant, timely, and aligned with your organization’s messaging. Because the email comes from a known sender in a real conversation, the banner gains more trust and visibility-and avoids spam filters entirely.
Rather than interrupting a recipient’s inbox, these banners naturally accompany authentic communication, making them more likely to be noticed and engaged with.
