System Consolidation

Email infrastructure sprawl leads to lost data, deliverability blind spots, inconsistent sender reputation-and unnecessary operational costs. SH Consulting’s System Consolidation service is designed to fix that.
We work with organizations that rely on multiple ESPs, legacy mail transfer agents (MTAs), third-party tools, and fragmented reporting systems-and help them move toward a simplified, unified, and scalable email infrastructure that is easier to maintain and more cost-effective to run.

This includes not only the platforms that send your emails, but also the full supporting ecosystem-DMARC vendors, DNS and authentication tools, webhook processors, security layers, monitoring systems, and anything else that touches or influences email performance and email security.

Whether you’re juggling SendGrid, Mailgun, Amazon SES, or a homegrown MTA - or you’re just trying to migrate off a deprecated system while keeping inbox placement stable - we’ll build the technical and strategic plan to get you there safely and quickly

What We Do

Conduct a deep discovery of every system that sends or supports email across your organization

Assess ESP usage, message types, sender profiles, and stack dependencies

Identify redundant tools, data silos, and budget waste

Audit DMARC vendors and DNS-based infrastructure

Analyze webhook pipelines, suppression logic, and visibility gaps

Provide a risk-weighted migration strategy with warm-up timelines

Suggest optimal ESP(s) based on technical needs, cost, and future goals

 Build volume segmentation and traffic pacing plans to avoid reputation dips

Set success metrics, dashboards, and failure recovery plans

Work alongside your team to execute and validate every step

Who This Is For

Companies using 2+ ESPs (e.g., Mailgun + SendGrid) without centralized monitoring

Teams moving off Mailchimp, SparkPost, legacy MTAs, or other ESPs

Businesses that acquired others and inherited messy infrastructure

Organizations with siloed tools for authentication, suppression, and reporting

Product teams preparing for scale who need a clean, unified platform

Leaders aiming to cut costs by consolidating tools and vendors

Why It Matters

A scattered email infrastructure means inconsistent reputation signals, fractured data, inefficient workflows-and rising bills. SH Consulting helps you consolidate with confidence, reduce platform overhead, and regain control over your architecture without sacrificing email performance or deliverability.

We bring deep technical knowledge, deliverability expertise, and hands-on execution to unify your email system and turn it into a streamlined asset that scales efficiently-and costs less to operate.
