Several factors can impact the accuracy rate of an email marketing campaign:
1. Email List Quality: An up-to-date and clean email list minimizes bounces and increases deliverability. 2. Content Relevance: Relevant and personalized content is less likely to be marked as spam. 3. Sender Reputation: A good sender reputation with ESPs is crucial for high accuracy rates. 4. Authentication Protocols: Implementing protocols like SPF, DKIM, and DMARC ensures your emails are authenticated and trusted. 5. Frequency: Over-sending can lead to higher unsubscribes and spam complaints, reducing accuracy.
