    Rocketseed Email Signature Generator: FAQ’s

    What is an email signature?

    An email signature is the personalised block of text automatically appended to an email as a ‘sign off’. It provides recipients with the sender’s contact information such as full name, job title, telephone number and email address. It can also include a headshot, a brand logo and links to social media profiles and website pages, such as a homepage or blog.

    Why is an email signature important?

    A business email signature is important for ensuring all employee emails look professional and for increasing brand recognition amongst recipients. Email signatures also enable recipients to engage with your brand, using clickable links to drive traffic to your website and social media profiles. The addition of disclaimers also ensures that your signatures keep all your business email legally compliant.

    Who needs to use an email signature?

    Anyone with an email address can use an email signature. In a business context, email signatures should be used by everyone from the single entrepreneur to all email-using employees of multinational enterprises to present a clear brand image on email. Whether your business has 10 employees in a single office or 10,000 spread across the globe, Rocketseed ensures complete email signature brand consistency via centralised control.

    What size should an email signature be?

    We recommend an email signature size of a maximum width of 650 pixels, and a maximum height of between 90 and 150 pixels. Rocketseed email signature generator facilitates this via its optimised email signature template size.

    What should a business email signature include?

    Keep your email signature on-brand, clean and simple, including all the most relevant information. Try limiting contact information to just three or four lines of text, alongside branded and interactive design elements. Your signature can include:

    • Your full name and job title
    • Contact details including office address, office and mobile telephone numbers
    • Company logo
    • Headshot
    • Social media links
    • Website links to your homepage, landing pages, newsletter sign-up or blog
    • Industry accreditations if appropriate
    • Legal disclaimer

    How do I add a logo to my email signature?

    Adding your brand logo to your email signature is simple with Rocketseed email signature creator. If your business logo is changed then you can centrally update all employee signatures with the new logo simultaneously using Rocketseed.

    How do I add a photo to my email signature?

    It’s simple to add a headshot photo to your signature using Rocketseed’s email signature maker.

    Which is the best font to use for an email signature?

    For a professional email signature, you need to use one of the ‘web safe’ fonts that are supported by all browsers and will always display correctly. Choose the ‘web safe’ signature font that best meets your business brand guidelines. You should also ensure that you use font sizes and colours that are clear and easy to read.

    These are all web safe fonts: Arial; Verdana; Georgia; Tahoma; Courier; Times New Roman; Trebuchet; Palatino; Lucida.
