There are several reasons why discrepancies might occur in email marketing:
Tracking Issues: Different email service providers (ESPs) may use varied tracking methods, leading to differences in metrics. Email Client Variability: Different email clients (e.g., Gmail, Outlook) render emails differently, which can affect how users interact with the emails. Data Collection Methods: The way data is collected and reported can vary between tools and platforms. Spam Filters: Emails might be filtered as spam, affecting open and click-through rates. List Quality: The quality and segmentation of your email list can impact engagement rates.
