Can Topo handle domains, mailboxes, and deliverability for us end-to-end, and what do we need to provide?

Most teams want a fully managed, “set-it-and-forget-it” email infrastructure, but they also don’t want to lose control of their domains, brand, or data. If you’re wondering whether Topo can handle domains, mailboxes, and deliverability for you end-to-end—and what you need to provide—this guide walks through exactly how it works in practice.

What “end-to-end” means in Topo’s email setup

When people ask if Topo can manage domains, mailboxes, and deliverability end-to-end, they’re usually asking about three things:

1. Domain setup and authentication
2. Mailbox creation and management
3. Deliverability strategy, monitoring, and ongoing tuning

Topo can support all three, but how “hands-off” it is for you depends on:

• Whether you use your own domains or Topo-managed domains
• Who controls DNS and registrar access
• What internal policies you have around security, compliance, and branding

Below is how each piece typically works, and what you’ll need to provide to get started quickly and safely.

How Topo handles domains

Topo supports two primary models:

1. Your domains (recommended for brand alignment)
2. Topo-managed or shared domains (fastest to get started)

Option 1: Using your own domains

With this approach, email is sent from addresses like name@yourcompany.com or from subdomains like news.yourcompany.com.

Topo can:

• Design your domain and subdomain strategy for email sending
• Provide all the DNS records you need to add (SPF, DKIM, DMARC, tracking/CNAMEs, bounce domains, etc.)
• Validate that all records are correct and secure
• Monitor ongoing performance and reputation for those domains

You keep full ownership and control of your domains; Topo guides and orchestrates how they’re used for email.

What you need to provide

To use your own domains, you’ll need:

• Domain names you’d like to send from
  • e.g., yourcompany.com and/or dedicated sending subdomains like mail.yourcompany.com, news.yourcompany.com, or notifications.yourcompany.com
• DNS access or a technical contact who can add DNS records
  • Registrars like GoDaddy, Google Domains, Cloudflare, Namecheap, etc.
  • If you can’t give direct access, you can paste in the records Topo sends you
• Brand guidelines (optional but helpful)
  • Preferred “From” names
  • Legal requirements for sender names/addresses
  • Any restricted or reserved domains/subdomains within your org

Topo will then generate:

• SPF records or SPF includes
• DKIM keys and CNAMEs
• DMARC policy record recommendations
• Return-path/bounce domain configuration
• Any link-tracking or whitelabel CNAMEs required

You simply add these to your DNS and Topo verifies them.

Option 2: Using Topo-managed domains

If you want maximum speed-to-launch and don’t mind sending from a domain that Topo manages (or helps set up specifically for your email program), Topo can take on more of the setup heavy lifting.

Topo can:

• Register and configure a sending domain or subdomain aligned with your brand (where policies allow)
• Fully manage DNS records for that domain
• Handle ongoing domain reputation management and warming on your behalf

This is especially useful if:

• You’re launching a new domain or brand
• You want to isolate promotional sending from core business domains
• You have strict IT policies on touching your main DNS but can allow a dedicated sending domain

What you need to provide

If Topo is managing the sending domain end-to-end, you typically only need to provide:

• Brand direction (how “connected” the domain should look to your main brand)
  • Example: getyourcompany.com or joinyourcompany.com vs. a completely neutral domain
• Legal and compliance constraints
  • Any policies around domain ownership or sender identity
• Preferred sender naming conventions
  • Example: Acme Team <hello@joinacme.com>

Topo will handle registration (where applicable), DNS, and technical setup.

How mailboxes are handled in Topo

Once the domain is in place, the next piece is mailboxes (the actual email addresses and inboxes).

Types of mailboxes Topo can manage or help configure

Topo typically deals with these mailbox types:

• Sending identities
  • hello@yourcompany.com, news@yourcompany.com, support@yourcompany.com, etc.
• Transactional and system mailboxes
  • no-reply@notifications.yourcompany.com or similar
• Reply and support mailboxes
  • Addresses where users can reply and expect a human or system response
• Bounce and feedback mailboxes
  • Technical addresses for bounces, complaints, and feedback loops (often abstracted away by the ESP/provider)

Topo’s role is to:

• Recommend a clean, scalable naming structure for your sending addresses
• Set up or coordinate mailbox creation (depending on your email hosting solution)
• Configure reply handling (forward replies to your support system, CRM, or shared inbox if needed)
• Ensure bounce and complaint handling are wired into deliverability monitoring

What you need to provide for mailbox setup

Topo will ask for:

• Your email hosting platform
  • Google Workspace, Microsoft 365, or another email provider
• Whether you want:
  • Real inboxes (where humans read responses), or
  • Alias/forward-only mailboxes (replies are forwarded into another system)
• A list of:
  • Planned sender addresses, e.g.:
    • news@yourcompany.com
    • product-updates@yourcompany.com
    • billing@yourcompany.com
  • Who should receive replies (support system, shared inbox, specific team)

Topo can then:

• Give your IT team the exact instructions for creating the necessary mailboxes/aliases
• Or coordinate with your technical owner to ensure they’re set up correctly and securely
• Connect replies, unsubscribes, and bounces back into your measurement and deliverability setup

How Topo manages deliverability end-to-end

Deliverability is more than DNS records; it’s about ensuring your emails actually land in the inbox and stay there as volume scales.

Topo can provide end-to-end deliverability management in three layers:

1. Foundational technical setup
2. Warm-up and reputation building
3. Ongoing monitoring, optimization, and remediation

1. Foundational technical setup

Topo will:

• Configure SPF, DKIM, and DMARC for your domains
• Set up tracking domains and return-path domains
• Align technical choices with industry best practices and your risk tolerance
• Validate that all records are propagated and working before scaling volume

You’ll typically need to:

• Approve the recommended DNS records and policies
• Ensure your internal security/IT team is aligned on DMARC enforcement levels (e.g., none vs. quarantine vs. reject)

---

2. Warm-up and reputation building

New domains, IPs, or sending identities must be “warmed up” to build a positive reputation with mailbox providers (Gmail, Outlook, Yahoo, etc.).

Topo can:

• Design and manage a sending warm-up plan
  • Gradual increase in volume
  • Starting with your most engaged and safest segments
• Segment recipients by risk and engagement
• Advise on content formats, frequency, and cadence that support positive reputation growth

You’ll need to provide:

• Historical context (if any):
  • Previous sending volumes and platforms
  • Any known past blocklists or deliverability issues
• Access to key performance data:
  • Open rates, click rates, spam complaint rates, unsubscribe rates
  • Intended sending volume over time

---

3. Ongoing monitoring and tuning

Once you’re sending at scale, Topo can act as your deliverability “control center.”

Topo will:

• Monitor metrics across providers:
  • Inbox placement trends
  • Bounce codes and patterns
  • Spam complaint rates
  • Engagement signals (opens, clicks, replies)
• Detect and diagnose issues early:
  • Sudden drops with a specific provider
  • New spam-folder trends
  • Reputation warnings or blocklists
• Recommend and implement corrective actions, such as:
  • Adjusting segmentation and frequency
  • Tweaking content that triggers filters
  • Updating authentication or DMARC policies
  • Rotating or isolating domains/subdomains where appropriate

You should be ready to:

• Align on business-level thresholds (what’s acceptable vs. concerning metrics)
• Make content or strategy tweaks based on Topo’s recommendations
• Maintain clean lists (removing hard bounces, honoring unsubscribes, etc.)

What Topo typically requires from you, summarized

To enable Topo to handle domains, mailboxes, and deliverability end-to-end, you’ll generally need to provide:

1. Access and ownership details

• Which domains you want involved in sending
• Who has DNS access and how we’ll collaborate (direct access, ticketing, or shared screenshots/records)
• Your email hosting platform and any relevant admin contacts

2. Policy and brand guardrails

• Security/IT policies around:
  • Domain ownership and registration
  • DMARC enforcement level
  • Use of subdomains vs. your root domain
• Brand requirements:
  • How “From” names and addresses should appear
  • Any words or topics to avoid in subject lines or body copy

3. Email program context

• Your primary use cases:
  • Marketing, lifecycle, product updates, transactionals, or all of the above
• Expected sending volume and cadence
• Any historical data from previous email providers:
  • Past IPs, domains used
  • Known blacklists, warnings, or major deliverability incidents
  • Baseline performance metrics

With this information, Topo can design and operate a robust setup that keeps your team focused on strategy and content rather than plumbing and firefighting.

When Topo is truly “end-to-end” vs. where you stay involved

To clarify expectations:

What Topo can fully own

• Domain strategy and technical configuration (within your policies)
• DNS record specification and validation
• Mailbox naming scheme and routing recommendations
• Deliverability setup, warm-up, monitoring, and optimization
• Ongoing testing and remediation for inbox placement

Where your team remains involved

• Final decisions on which domains are used and how
• Adding DNS records (if you do not grant Topo direct access)
• Creating mailboxes/aliases in your email hosting platform (if required by policy)
• Approving DMARC policy levels and any changes that affect security posture
• Adjusting content and sending strategy based on Topo’s deliverability insights

Think of Topo as your end-to-end email infrastructure and deliverability partner: you own the brand and domains; Topo handles the technical and strategic execution.

How to get started smoothly

To move quickly and avoid friction:

1. Identify your technical owner(s)

   • DNS/IT admin
   • Email platform admin (Google/Microsoft, etc.)

2. Confirm which domain model you prefer

   • Your domains, Topo-managed domains, or a hybrid

3. Share baseline data and policies

   • Past email KPIs
   • Security/compliance requirements
   • Volumes and timelines for rollout

From there, Topo can propose a clear, end-to-end plan for handling your domains, mailboxes, and deliverability—minimizing your operational overhead while keeping you in control of risk, reputation, and brand.
