For ESPs and Marketing Automation Companies
of ESPs Choose PowerMTA™
ESPs are often contractually bound to meet stringent Service Level Agreements for delivering end-customer email campaigns. PowerMTA™ provides a sophisticated solution for multi-stream delivery execution.
Automated and policy-driven messaging, combined with rock-solid sending architecture, have proven to be critical for organizations worldwide as they move away from dependence on third party platforms. PowerMTA™ allows enterprises to make this transition with confidence and ease.
PowerMTA™ v4.5 includes new advanced functionalities that permit greater flexibility and delivery control to maximize performance and deliverability.
The new PowerMTA Management Console (PMC) v1.5 supports all new PowerMTA™ v4.5 features, including IP-based reporting, saved reports, configurable session timeouts and advanced reporting filters (including sets and regular expressions).
PowerMTA™ now supports the ability to schedule deliveries through an easy-to-use header. This comes in handy for those times when you have spent a long time building a campaign or if you need to adhere to strict delivery windows.
IP rate limiting permits controlling the number of attempted recipients on a per-hour, per-minute and per-second basis for each IP address for each domain/VirtualMTA. This is primarily used by sites that define multiple IPs in a single VirtualMTA, and want to limit the attempted delivery rate for each IP address in the VirtualMTA to the respective domains.
PowerMTA™ now supports the ability to auto-increase cold VirtualMTA mail volumes with a list of daily limits.This makes it easy to have a “set it and forget it” configuration for warming new IP addresses.
To help optimize DNS usage during peak sending times,PowerMTA™ now offers the ability to precache predefined domain names to ensure the DNS name is always available.
Top-level features for v4.5 include
- Custom retry intervals
- Backoff reason insight
- Enhanced job control (pause & resume)
- Precached domains support ensures DNS info always available
- Recipient events listing to aid in real-time queue diagnostics
- Reverse DNS check on inbound connections
- Address suppression lists defined with global tag allow senders to use multiple suppression lists
Flawless High-Volume Delivery Windows with Scheduled Delivery Control
Recipient engagement has become the single most critical element in maximizing inbox placement, and onlyPowerMTA™’s Scheduled Delivery Control™ allows you to truly take advantage of time-based engagement metrics.
Pushing this intelligence from CRM systems toPowerMTA™ lets you create and submit the full campaign hours or even days in advance. You can even define multiple start and stop time windows for a single message.
Unmatched Architecture for Unmatched Features
PowerMTA™ handles core tasks with greater efficiency, intelligence and control than general-purpose open-source MTAs. Not only is PowerMTA™ the industry leading outbound sending platform, it can also handle inbound reply messages that have bounced. The performance, integration capabilities, and native intelligence you get built into PowerMTA™ give you a distinct advantage over your competitors who use general-purpose email relays.
PowerMTA™ also easily integrates with CRM packages such as SalesForce. You can transfer messages to PowerMTA™ for delivery through a standard interface based on SMTP, or through APIs available in common programming languages.
TLS Encryption over SMTP
As the sending industry moves to a more secure and encrypted sending model, you will be increasingly required to track whether a message was delivered over a secure socket and, if so, what protocol and cipher were used. PowerMTA™ solves this problem by utilizing the Transport Layer Security (TLS) protocol over SMTP for certificate-based authentication that provides security-enhanced data transfers using symmetric encryption keys.
Advanced TLS handshake performance optimizations benefit high-volume senders by allowing you to use opportunistic TLS globally while having thousands of simultaneous outbound connections active. This feature is available with the Enterprise license.
