Short Links in Email Marketing: Best Practices That Protect Deliverability

Email is still one of the most effective ways to reach customers, and links are how emails turn into action. Short links can make emails cleaner and easier to track, but they need to be used thoughtfully, because the way links appear in an email can affect whether it reaches the inbox at all.

Here's how to get the benefits without the risks.

Where short links help in email

Plain-text emails

Plain-text emails show the full URL. A 150-character tracking URL looks messy and can break across lines. A short link keeps the message readable:

Visible links people may type or remember

If a link appears as text that people might copy, type or remember later, such as in a signature, a footer or an event reminder, a short custom link is easier to use.

Email signatures

Your signature goes out with every email you send. A clean link to your booking page or link-in-bio page looks professional and can be tracked.

One-to-one emails

In sales and support emails, short links keep messages tidy and show you whether a customer opened the resource you sent.

Tracking outside your email platform

Most email marketing platforms track clicks for you. Short links are useful when you send emails from a regular inbox, such as Gmail or Outlook, where you don't get click tracking. See link click analytics.

Where to be careful: deliverability

Spam filters look closely at links. Public link-shortening domains are shared by many users, and some spammers abuse them to hide destinations. Because of this, some filters treat links on public shortener domains with extra suspicion, especially in bulk emails.

Practical guidance:

• For bulk marketing emails sent through an email platform, link buttons and text directly to your own website, and let the platform track clicks. Your own domain builds a sending reputation that shared domains can't.
• Use short links where the visible text matters, such as plain-text versions, signatures and one-to-one messages.
• Don't hide destinations. Make the link text describe where it goes, like "View your order" or "Read the full guide".
• Avoid stacking redirects. Your email platform may already wrap links in its own tracking redirect. Adding a shortener on top creates two hops, which is slower and looks more suspicious to filters.
• Test before sending. Send to test inboxes at several providers, such as Gmail, Outlook and Yahoo, and check that the email lands in the inbox.

Writing email links that get clicked

The words around a link matter more than the link itself:

1. Use descriptive link text. "Download the checklist" beats "click here".
2. Make the main action obvious. One clear primary button works better than ten equal links.
3. Repeat the key link. Put your main call to action near the top and again at the end.
4. Make links easy to tap. Buttons should be large enough for a thumb on mobile.
5. Match the promise. If the email promises a discount, the link should land on a page showing that discount.

Track email campaigns properly

To understand what happens after the click, combine links with UTM parameters:

• utm_source=newsletter
• utm_medium=email
• utm_campaign=october_offer
• utm_content=header_button or footer_link to compare placements

In bulk emails, add UTMs to the direct links. In plain-text and one-to-one emails, add UTMs to the long URL first, then shorten it.

A quick checklist

• Plain-text version uses short, readable links
• Bulk campaign links point to your own domain
• Link text describes the destination
• No double redirects
• UTMs added and tested
• Test emails checked in several inboxes
• Every link clicked once before sending

Frequently asked questions

Do short links cause emails to go to spam?

They can raise the risk in bulk emails because public shortener domains are sometimes abused by spammers. For bulk campaigns, link directly to your own domain. Short links work well in plain-text emails, signatures and personal messages.

Should I use short links in my email signature?

Yes. A short custom link in your signature looks tidy and lets you see how many people click it.

How do I track clicks if I send emails from Gmail or Outlook?

Use short links. Each short link records clicks, countries, browsers and operating systems, so you can see engagement even without an email marketing platform.

Can I use QR codes in emails?

You can, but people reading an email on their phone can't scan a code on the same screen. Use a normal link in emails, and save QR codes for print and screens. See how to create a QR code for any link.
