‍

At a glance

This blog post provides a four-step guide to replacing email with a secure, branded client portal. The process involves setting clear goals, running a small pilot, and choosing a portal with automation features like Moxo. Key actions include customizing the portal with your brand, setting up security measures like two-factor authentication, and cleaning and migrating data. A critical component is a structured communication plan to inform clients about the switch at multiple intervals before and after launch. 

How email is killing productivity for your organization

How many hours did your team lose last week digging through email threads for that one attachment? Too many. Email is great for a quick note, but it’s a terrible project manager and an even worse filing cabinet. It creates friction, security risks, and a disjointed experience for the people who matter most: your clients.

Moving to a client portal isn't just an upgrade; it’s a strategic shift. It’s about creating a single, secure, and professional space for every client interaction. This checklist is your roadmap to a smooth, disruption-free migration that your clients will thank you for.

The complete client portal migration checklist

Follow these four phases to move from email to a modern client portal without interrupting business.

Phase 1: Pre-migration planning & strategy

This is the foundation. Get this right, and everything else falls into place.

• Define clear objectives: What does a successful migration look like? Is it reducing support emails by 40%? Achieving 90% client adoption in the first quarter? Set concrete KPIs you can measure.
• Assemble your migration team: This isn’t a solo mission. Assign a project lead, a technical lead to handle the software side, and a communications lead to manage client messaging.
• Audit your current state: Map out every client workflow that currently runs on email. Identify all the types of data being exchanged—contracts, invoices, project files, support requests. You can't fix what you don't see; use a business process audit guide to structure this step.
• Choose the right portal: Your portal should be secure, easy to brand, and integrate with your existing tools. A platform with a workflow builder is non-negotiable for automating repetitive tasks.
• Develop a phased rollout: Don’t flip the switch for everyone at once. Start with a pilot group of trusted clients. They can provide feedback, and you can iron out kinks before a full launch.

Phase 2: Technical setup & data migration

Now you build your new digital front office.

• Configure your portal: Add your company logo, brand colors, and set up a custom URL. This isn’t just software; it’s your client’s new home base. It needs to feel like you.
• Set up security: This is paramount. Enable two-factor authentication (2FA) and define user permissions. The whole point is to be more secure than email, so don't skip this. Moxo’s enterprise-grade security and granular permissions ensure that only the right people see the right information.
• Create a data migration plan: Decide what data needs to move (e.g., active project files) and what can be archived. Clean your data before migrating to avoid carrying over old junk.
• Run a test migration: Create a sandbox environment and move a sample of client data. Check for errors and verify everything is intact. This step catches problems before they affect real clients.
• Train your internal team: Your team must be experts on the portal before your clients are invited. Give them scripts to answer common questions and make sure they understand the back-end operations.

Phase 3: Client communication & onboarding

This is the most critical phase for a disruption-free launch. Over-communicate with clarity and enthusiasm.

• Create a communication cadence:
  
  • 30 days before launch: Send an announcement email. Explain the change, focus on the benefits for them (e.g., "24/7 access to files," "better security"), and give a firm launch date.
  • 7 days before launch: Send a reminder with a link to a short video tour or a one-page "quick start" guide.
  • Launch day: Send the official invitation email with a clear link and simple login instructions.
  • 7 days after launch: Send a follow-up email to check in, ask for feedback, and offer support.
• Set a hard cut-off date for email: Be direct. "As of [Date], all project communication will move to the portal to ensure efficiency and security." Set up an auto-responder on old email inboxes that gently redirects clients to the new portal. This simple step is what makes the change stick.
• Onboard with precision: Firms like BNP Paribas cut client onboarding time by 50% by unifying every step - from messaging to document exchange and digital signatures - in their Moxo-powered portal. An actionable client portal turns onboarding from a series of emails into a single, guided workflow.

Phase 4: Post-migration support & optimization

You’ve launched. Now it's time to make it stick and get even better.

• Monitor adoption & KPIs: Use your portal's analytics to track login rates and feature usage. Are you hitting the goals you set in Phase 1?
• Gather client feedback: Use simple surveys to ask clients about their experience. Act on their feedback to show you're listening and continuously improving the experience.
• Reinforce the new way: If a client emails you a file, reply with, "Thanks! Can you please upload this to the portal here [link] so we have it on file?" Gently but firmly guide everyone to the new process. Moxo’s mobile app makes this easy for clients, as they can manage tasks and upload files from anywhere.
• Plan for v2.0: Use the data and feedback you’ve gathered to plan future enhancements. A great client portal evolves with your business.

FAQs

Can Moxo integrate with our CRM and document tools?

Yes. Moxo connects to major CRMs like Salesforce and document systems like Dropbox through native connectors and APIs. This allows your team to keep data in sync between your portal and your core systems without manual uploads, ensuring workflows and client records remain perfectly linked.

How secure is the Moxo client portal?

Moxo is built with bank-grade security, including end-to-end encryption, role-based access controls, and comprehensive audit trails that track every action. Centralizing document exchange and e-signatures in the portal eliminates the risks of sensitive data being scattered across insecure email threads, helping you meet strict compliance requirements.

How long does implementation take?

Most teams can launch a focused pilot with a Moxo workflow template in just a few days. A full rollout to all clients typically happens over a few weeks as you refine your processes. The no-code workflow builder allows you to set up and adjust onboarding or approval sequences quickly, without needing IT support.

Why use a client portal instead of email and shared drives?

Email and shared drives were not designed for structured business workflows. A client portal combines messaging, file sharing, task management, and e-signatures into a single, guided flow with automated notifications and audit logs. Moxo customers report faster project cycles and fewer errors because every step is tracked and centralized.

Will my clients actually use the portal?

Client adoption is strong because a Moxo portal is a private-label experience that is intuitive and mobile-first. Instead of chasing confusing email threads, clients are guided through clear tasks with automated reminders from Moxo’s agentic AI, leading to higher engagement and faster responses. For example, Standard Chartered saw over 65% of transaction approvals shift to their Moxo-powered digital hub.
