ESP redundancy offers several benefits, including:
Reliability: Ensures that your email campaigns are always delivered, even if one ESP experiences downtime. Improved Deliverability: Diversifies your sending reputation across multiple IPs and domains, which can improve overall email deliverability. Flexibility: Allows you to leverage the strengths of different ESPs, such as better segmentation or advanced analytics. Cost Efficiency: By spreading your campaigns across multiple ESPs, you may be able to optimize your costs and avoid over-reliance on a single provider.
