How to Run Email Signature Campaigns

An email signature campaign adds a linked banner below employee contact details. Use it to promote a launch, event, job opening, or new piece of content in messages your team already sends.

Why Use Signature Campaigns

Signature banners sit inside active conversations with customers, prospects, and partners. They also use existing outbound email instead of a separate media budget.

• Attached to outbound email. The banner travels with messages sent by employees using the assigned signature.
• No media spend. You use email your team already sends.
• Relevant context. Recipients are already in conversation with your team.
• Centralized. One admin can update the banner across every signature assigned to the campaign.

Creating Your First Campaign

Setting up a campaign in Lastline follows five steps:

1. Navigate to Campaigns in your dashboard.
2. Click Create Campaign and give it a name.
3. Design your banner using the built-in banner maker or upload a custom image.
4. Set the destination URL, which is where recipients land when they click.
5. Set start and end dates, then activate. The banner is attached to your signature template and deployed to all employees who use that template.

Designing Effective Banners

Your banner competes with the rest of the email for attention. Follow these principles:

Keep it simple

One message, one call to action. Don't try to cram multiple offers into a single banner. Use a short headline, a supporting line, and a clear button.

Use brand colors

Your banner should feel like a natural extension of the signature, not an afterthought. Match your brand palette and typography for a cohesive look.

Size it right

Recommended banner dimensions are 600 x 150 pixels. This renders well across Gmail, Outlook, and Apple Mail without taking up too much vertical space.

Reaching the Right Audience

Campaigns are linked to signature templates. Since Lastline lets you assign different templates to different groups using assignment rules, you can control which employees display a particular campaign by choosing which template it's attached to.

For example, your sales team's signature template can carry a webinar banner, while marketing's template promotes a new blog post. Both can run at the same time without overlap.

Measuring Results

Every banner click is tracked automatically. In your campaign dashboard, you can see:

• Total impressions: How many emails carried the banner.
• Click count: How many recipients clicked through.
• Click-through rate: The percentage of impressions that became clicks.
• Top performers: Which employees' emails generate the most clicks.

Compare the results when you change a headline, image, CTA, audience, or schedule. Change one variable at a time so you know what affected the click rate.

Campaign Ideas to Get Started

Common campaign uses include:

• Product launches: Announce new features or products with a banner linking to the announcement page.
• Events and webinars: Link to the registration page for an upcoming event.
• Case studies: Link to a customer story or case study.
• Hiring. Promote open positions with a "We're hiring" banner.
• Seasonal promotions: Promote a dated offer or limited-time discount.
• Content marketing: Link to your latest blog post, whitepaper, or guide.

Give every campaign a start date, end date, and destination URL. With Lastline's campaign scheduling, scheduled banners activate and expire without another deployment.
