Subject: Quick question about our new domain 👋
Hi Jordan, I ran into a problem with my email. I sent a launch announcement to our clients, and most of them found it in their spam folder. Our domain is only a few weeks old and has never sent campaigns before. My guess is the new domain, but I’ve never warmed one up and don’t know where to start.

How to Create a Free Email Signature in 4 Steps
You can create a free email signature with Warmy in about a minute, with no account needed. The four steps are below, and the tool sits right above them.
- 1
Pick one of our four templates. If you switch later, nothing you’ve typed gets lost.
- 2
Type your name and title, then only the contact details you actually want people to use.
- 3
Add the company name. The address is optional, unless you’re emailing people in the US.
- 4
Add a photo and links if you like, then copy the result as HTML or plain text and paste it into your email client.
A Free Email Signature Builder Made by Deliverability Experts
Plenty of tools make a nice-looking signature. We look at it the way we look at every email: what does the recipient see, and what does the receiving server see? That’s the work we do every day for 35,000+ businesses.
Look Professional From the First Email
With a clean professional email signature at the bottom of every message, nobody has to dig back through a long thread to find your phone number. In effect, it’s your business card.
Lightweight by Design
The templates are written in simple, email-friendly HTML and contain only the links you add, with no tracking of any kind. We can’t promise a signature will get you into the inbox, since no signature can, but ours won’t add weight or risk to your emails.
Ready in About a Minute
It takes about a minute, since all you do is pick a template, type in a few details and copy the result as HTML or plain text. There’s no need for design skills or an email signature designer, and you won’t touch any code.
Your Signature Looks Great. Does Your Email Reach the Inbox?
People do trust a properly signed email more. Whether that email reaches the inbox is another matter. That’s decided by your domain’s reputation, your SPF, DKIM and DMARC records, and how people react to what you send, and a nice signature can’t make up for problems there.
That’s the part Warmy handles:

What Our Customers Say
The platform’s warmup processes make sure that our cold emails don’t bounce into spam filters. It also makes use of AI behavior tracking as we’re sending which is great for campaigns scaling. It’s also really valuable to be able to track open rates and responses.
What Is an Email Signature Generator?
Put simply, an email signature generator writes the signature code so you don’t have to. You fill in a few boxes, it hands you a finished signature, and you paste that into your email client. Anyone who has tried building one by hand in Outlook’s signature editor knows why that’s worth having.
Some sites call it an email signature creator, others an email signature maker or a signature block generator. It’s the same thing. Ours comes from the team behind Warmy’s warm-up and deliverability platform, so we care how the code behaves in real inboxes and not only how it looks in the preview.
HTML Email Signature vs. Plain-Text: Which Should You Use?
Most people should use an HTML email signature for day-to-day email. The logo and clickable links are the whole point of it. Cold outreach is different, and on a first cold email we’d go with a plain-text email signature every time. Warmy’s generator gives you both: Copy as HTML and Copy as text.
| HTML signature | Plain-text signature | Image-only signature | |
|---|---|---|---|
| What it is | Formatted layout with photo or logo, icons and clickable links | Text only, no images or code | Your whole signature saved as one picture |
| Clickable links | Yes | Most clients turn URLs and emails into links automatically | No |
| If images are blocked | Text and links still show | Not affected | Nothing shows |
| Best for | Client communication, replies, warm leads | Cold first touch, sequences, Gmail mobile signature | Not recommended |
We’d skip image-only signatures altogether. Plenty of people read email with images switched off, and they’d just see an empty box where your details should be. And filters have long treated emails that are mostly images as likely junk. A proper HTML email signature generator avoids that by keeping your name and number as real text.
What to Include in a Professional Email Signature
Keep a professional email signature to the basics. Your name and role, the company, and a phone number is plenty. A photo or logo, a website link and one social profile are optional extras. Keep it to 3–6 lines.
| Element | Include? | Tip |
|---|---|---|
| Full name | Always | Use the name people know you by |
| Job title | Always | Keep it short: “Head of Sales”, not the whole org chart |
| Company name | Always | Link it to your site only if you don’t have a separate website link |
| Phone number | Recommended | One number, with the country code if you work internationally |
| Website | Recommended | One link to your main site, on the same domain you send from |
| Email address | Optional | The recipient already has it, but it helps when your email gets forwarded |
| Photo or logo | Optional | Small and light; skip it in first-touch cold emails |
| Social icons | Optional | 1–3 profiles you actually use; LinkedIn first for B2B |
| Postal address | Required in commercial email to US recipients | The US CAN-SPAM Act requires a valid physical postal address in commercial messages, and that includes cold sales emails. The signature is the natural place for it. Other countries have their own rules. |
| Legal disclaimer | Depends | Only if your industry or company requires it |
Business, Personal and Cold Email Signatures
It depends on who’s reading. For clients, use the full business email signature. Personal email can get away with something shorter, and cold outreach works best with the lightest version.

Email Signature Best Practices for Deliverability
It’s rare for a well-built signature to send an email to spam by itself, although it does add code, images and links to every message, and filters look at all of that together with your domain reputation and authentication. The habits below keep it from adding risk.
Images should stay small. Around 50 KB each is a sensible ceiling, as a PNG or JPG on a reliable domain.
Limit links. Two or three links in a signature is usually enough. Every URL is something filters can check against blocklists.
Don’t turn the signature into one image. If images are blocked, it disappears, and mostly-image emails look like junk mail to filters.
Leave tracking out of the signature. Redirect links and tracking pixels add weight and can look suspicious. Click tracking is better handled by your sending tool, if you need the data at all.
Link to your own domain, because links that match the domain in your From address look consistent. Link shorteners don’t.
Length matters less than people think, up to a point. Gmail allows 10,000 characters per signature, but the bigger risk is the whole email growing past roughly 102 KB, the size at which Gmail is widely reported to clip messages.
Stick to Arial, Helvetica, Georgia or Verdana if you want the signature to look the same for everyone.
And test before a big send. A seed list will tell you where the email actually lands.
Expert tip
Daniel Shnaider
Co-Founder, Warmy
What should a signature look like in a cold email?
“In a cold email, your signature has one job: prove you’re a real person at a real company. Keep it to three or four lines of plain text — name, title, company, one link — and save the logo and the social icons for when the conversation has started.”
Good example
Alex MorganHead of Sales, Example Coexample.com · +1 555 010 0100123 Main St, Austin, TX 78701
What signature mistakes hurt deliverability most often?
“The mistakes I see most often are link shorteners, links to a domain you don’t send from, and a stack of social icons — each one adds a link and an image to an email that should look like a note from one person. The worst case is a signature that’s a single image: to a spam filter, that’s text you’re trying to hide.”
Images or no images on the first email?
“No. In the first email, skip the logo, the headshot and the banners: many inboxes block images from senders they don’t know, so people see empty boxes, and an image-heavy email from a stranger reads like marketing. Add the logo once the prospect has replied.”
How to Set Up a Cold Email Signature
For the first email in a sequence, use Copy as text and keep your name, title, company and one link. Anyone emailing US recipients should leave the postal address in as well. The photo and logo can come back once you’re replying and following up. Running AI SDRs or lots of mailboxes? Warm up each new inbox before it sends a single cold email.

Pasting is the easy part. Finding the right settings screen is where people get stuck, so here’s where it lives in each client.

Email Signature Generator FAQ
It’s the bit at the bottom of an email that says who you are and how to reach you. Some people add a photo, a logo or social links. Once it’s set up, your email client adds it to every new message by itself.
Yes. It’s a free email signature generator with no limit on how many signatures you make, and we never ask for a credit card.
No. Open the page, pick a template and copy your signature when it’s ready. The checkbox under the preview is optional and only for people who want product tips from Warmy.
Yes, in all four. Classic Outlook for Windows is the only one that’s a bit fussy, because it renders HTML through Word and can shift the spacing slightly. Send yourself a test email to check.
When emails already go to spam, the signature is rarely the cause. It’s usually the domain’s reputation, authentication that isn’t set up, or recipients not engaging. Our free deliverability test will show you which one.
Yes, in step 4. LinkedIn is there too, along with your other social profiles.
Go for roughly 200×200 px on a headshot and 200–300 px across for a logo. They’re shown smaller, which keeps them crisp on sharp screens, and each file should stay near 50 KB.
Yes. Use one template for everyone and just change the name and title. Agencies can keep each client’s mailboxes and warm-up in their own Warmy workspace.
Yes, it works in a phone browser. The Gmail app is the catch, since its mobile signature only takes plain text, so use Copy as text there.
Open the generator again, rebuild it with the new details and paste it over the old one. A minute, more or less.
