Implementing ESP redundancy involves several steps:
Choose Multiple ESPs: Select at least two reliable ESPs that can handle your email volume and meet your marketing needs. Integrate ESPs: Use tools or software that can integrate multiple ESPs into your email marketing platform, making it easy to switch between providers. Segmentation: Segment your email list and distribute your campaigns across multiple ESPs to balance the load and reduce the risk of issues. Monitoring: Continuously monitor the performance of each ESP and be prepared to switch to a backup provider if any issues arise.
