Deliverability is
a chain of decisions.

Sky uses Email Engine—existing software with 23 sending-provider connections—to connect approved SMTP services, supported provider APIs and your own mail servers. We bring sending, testing and receiver signals into one operating process. Choose a starting point, or let us trace the full route.

Where should we look first?

01
DIAGNOSE

Deliverability audit & recovery

When delivery changes, it is tempting to swap IPs, rewrite subject lines or buy another tool. We start with evidence: transport logs, authentication, receiver behavior, complaints and representative placement tests.

02
CONNECT

SMTP integration & setup

Bring your approved SMTP service or sending server into one campaign and delivery workflow. Sky uses Email Engine to set up schedules, route messages and bring available bounces and complaints back into the process.

ESTABLISH

Domain & IP warmup planning

We have managed domain and IP warmups in our own sending operations. For a new approved route, we establish identity, use permissioned engaged audiences, run placement samples and adjust volume to receiver responses—not a calendar alone.

Monitoring & sender operations

We built this monitoring discipline inside our own sending operation. Sky connects the available sending events with authorized Google Postmaster Tools, Yahoo complaint feedback and Microsoft SNDS/JMRP signals. We distinguish individual complaints from aggregate trends before acting.

02CONNECTED SENDING, EXPLAINED

Keep your sending account.
Get one clear workflow.

Email Engine gives Sky an established way to connect approved SMTP services, supported provider interfaces and self-managed mail servers. We handle the agreed setup, campaign controls and available feedback. You keep your provider relationship, your audience and the decision to send.

01 / AUTHENTICATED SMTP

Connect your SMTP service

We configure sending identity, the relay connection, schedules and routing for the account you are approved to use. Provider limits and permitted traffic still apply.

02 / SUPPORTED INTEGRATIONS

Use an existing connection

Where your provider supports it, Sky connects its available sending and event interfaces so the same workflow can reflect bounces and complaints.

03 / SELF-MANAGED SENDING

Keep your own servers

If dedicated IPs and an MTA are appropriate, we work with the server configuration and queue responses you already control.

These are software connection options, not vendor partnerships. A connection does not grant a sending account, IP access, traffic approval or a guaranteed inbox result.

THE SIGNALS BEHIND THE SEND

Three inbox providers.
Three different kinds of evidence.

Sky combines sending-system events with the receiver information a client is authorized to access. A complaint report can sometimes identify an address; a postmaster trend often cannot. The response must fit the evidence.

01 / Gmail

Google Postmaster Tools

WHAT IT SHOWS

Aggregate spam-rate, authentication and delivery-error signals. Campaign-level Feedback-ID reports may appear when reporting conditions are met—not a list of individual people who marked mail as spam.

WHAT SKY CAN DO

Compare dates and campaigns with sending logs; change targeting, identity or pacing based on the pattern.

Access needed: Verified sending domain + authorized dashboard or API access

How this provider reports data
02 / Yahoo

Sender Hub / Complaint Feedback Loop

WHAT IT SHOWS

For eligible mail, complaint reports can identify a recipient who marked a message as spam.

WHAT SKY CAN DO

Suppress the identified address on every applicable sending route, then inspect audience source and frequency.

Access needed: DKIM-signed mail + an enrolled, verified sending domain

How this provider reports data
03 / Microsoft

SNDS + JMRP

WHAT IT SHOWS

SNDS provides IP-level sender data. JMRP reports user-marked-junk messages when the program is enabled; these are different feeds.

WHAT SKY CAN DO

Investigate IP or traffic changes and suppress an identifiable complainant when a report permits it.

Access needed: Authorized access to sending IP data; JMRP enrollment for complaint reports

How this provider reports data

These are supported operating sources, not automatic access to a client account. Sky confirms the client’s domain/IP permissions, available integrations and what can be automated versus reviewed manually before agreeing on monitoring coverage. Sending-service complaints and bounces are reconciled separately from mailbox-provider dashboards.
