What makes a good email signature

• Keep it under 4 lines — anyone using a mobile email client will thank you
• Include one clear primary contact method, not all of them
• Skip animated GIFs, inspirational quotes, and disclaimers longer than the email
• Stick to email-safe fonts — Arial, Helvetica, Georgia, Verdana, Tahoma
• Do not use an image for the text of your signature — bad for accessibility and dark mode
• Link text once; do not over-link or the signature looks spammy

Email signature best practices for small businesses

For a small team, consistency across the team matters more than each individual signature being unique. Everyone gets the same template, the same color, the same font — swap only the name, title, and contact info. That is how a small team looks like a company instead of five people using five different email clients.

For customer-facing roles — support, sales, customer success — keep the signature minimal and one click from a reply path (email or phone). The signature is not the marketing; the reply is.

Email signatures and brand consistency

If your team is sending emails from shared inboxes — support@ or hello@ — the signature is the only place the customer sees who is actually replying. Keep it consistent across the team and you look like a company. Keep it chaotic and you look like a group chat.

Auxx.ai lets teams set canned signatures per agent that pull from a shared brand palette, so support emails look the same whether Alex or Sam sent them.
