Email Marketing ROI
Email marketing ROI measures the financial return generated by email marketing efforts relative to their cost. For email signature marketing specifically, ROI considers the revenue or value generated from signature banner clicks and conversions against the cost of the signature management platform and campaign creation.
Key Aspects
High Returns
Email marketing consistently delivers among the highest ROI of any marketing channel, averaging $36-42 per dollar spent.
Measurable
ROI can be calculated precisely by tracking click-to-conversion paths from signature links to revenue events.
Low Cost
Signature-based marketing has minimal incremental cost since the emails are already being sent for business purposes.
Calculating Email Signature Marketing ROI
Email signature marketing ROI is calculated as: (Revenue from signature traffic - Cost of signature platform) / Cost of signature platform x 100. For example, if your signature management platform costs $200/month and signature banner clicks generate $2,000 in attributable revenue, your ROI is 900%.
The ROI of email signature marketing is typically very high because the marginal cost is low. Employees are already sending emails as part of their jobs — the signature marketing simply adds a promotional element to those existing communications. The primary costs are the signature management platform subscription and the time to design banners and manage campaigns.
