Several tools and services can help manage and reduce server load during email marketing campaigns:
SMTP Relays: Using SMTP relays can offload the email sending process from your primary server to dedicated email servers, reducing the load on your server. Email Service Providers (ESPs): ESPs like Mailchimp, SendGrid, and Constant Contact offer robust infrastructure to handle large volumes of emails efficiently. Load Balancers: Implementing load balancers can distribute the email sending tasks across multiple servers, ensuring no single server is overwhelmed. Content Delivery Networks (CDNs): CDNs can cache and deliver email content more efficiently, reducing the load on the primary server.
