Delivery Server
The delivery server is an essential component of your email marketing infrastructure, enabling you to send bulk emails, transactional messages, and automated notifications effectively. You have the flexibility to choose from different delivery servers, including third-party APIs and our custom SMTP Setup.
This article will guide you through the setup and management of delivery servers, explaining the various types of servers available, the setup process, and how to optimize their usage for email campaigns.
What is a Delivery Server?
A delivery server is a server through which your emails are sent. It acts as the intermediary between your email application and the recipient's mailbox, ensuring that your emails are delivered reliably and securely. Delivery servers are often configured to handle large volumes of emails and ensure compliance with internet service providers' policies for better inbox delivery.
You can add multiple delivery servers and control how emails are distributed among them. You can choose from several types of delivery servers, including well-known third-party email service providers (ESPs) and our custom SMTPs.
Types of Delivery Servers Available
1. SMTP
What is SMTP? SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails across the internet. It acts as a delivery server, allowing users to send bulk emails reliably. With an SMTP server, emails are processed, authenticated, and delivered to recipients' inboxes. Businesses and marketers use SMTP to ensure efficient email distribution and maintain a strong sender reputation.
At BulkEmailSetup, we provide a customized SMTP setup for our customers based on their selected plan. This ensures optimized email delivery and scalability for bulk email sending.
SMTP Creation Based on Plan
Basic Setup: Includes 1 SMTP setup for sending emails efficiently.
Advance Setup: Includes 3 SMTPs, allowing higher sending volume and improved email distribution.
Custom Setup: Can include multiple SMTPs with advanced configurations for large-scale email campaigns.
Each SMTP is configured with multiple dedicated IPs, domain authentication (SPF, DKIM, DMARC), and warm-up strategies to ensure high deliverability. The SMTPs are designed to align with best email practices, reducing the risk of blacklisting and improving inbox placement.
This SMTP creation approach allows our customers to scale their email marketing campaigns effectively while maintaining optimal sending reputation.
Requirements for SMTP Setup:
Hostname/IP address, Port, Username and password/key (for server authentication)
Additional IPs + Domains (for creating multiple SMTPs)
Benefits of SMTP Setup:
Complete control over your email sending infrastructure.
Ability to rotate IPs and domains as needed, minimizing the risk of blacklisting.
Cost-effective solution compared to third-party providers.
