Overview
Proton is a privacy-first encrypted productivity suite; Monday.com CRM is a sales and customer management platform. There is no shared CRM object model between them, which makes this migration less about record-for-record replacement and more about extracting the contact and calendar data that exists in Proton and remapping it into Monday.com CRM's People, Organizations, and Activity structures. We extract Proton Contacts as vCard records and Organizations as structured data, then map them into Monday.com CRM People and Companies. Calendar events migrate as meeting records. Proton Deal equivalents do not exist as a native object, so we discuss with the customer whether deal data exists in Proton Drive files or spreadsheets and whether it warrants a structured Monday.com Deals migration. We do not migrate VPN configurations, password vault entries, or email aliases as they have no CRM equivalent. Automations, workflows, and reporting dashboards do not migrate as code; we deliver a written inventory for the customer's admin to rebuild in Monday.com's native automation center and dashboard builder.

Object mapping
Each row shows how a Proton object lands in monday CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Proton
Contact
monday CRM
People (Contact)
1:1Proton Contacts include name, email addresses, phone numbers, physical addresses, and custom fields. We export contacts in vCard format and map each field to the corresponding Monday.com People column type. Proton labels (tag-style, color-coded) migrate as Monday.com tags applied to each People record. We validate email address format during transformation and flag any contacts with missing required fields before insert.
Proton
Organization
monday CRM
Organization (Company)
1:1If Proton Contacts contain organization affiliations, we extract the company name field and create Monday.com Organization records. The Proton contact's company affiliation maps to a Monday.com Organization Lookup on the People record. Organizations without an explicit Proton source are created as standalone Monday.com Organization records with name populated from the contact's company field and domain derived from the email address where available.
Proton
Calendar event
monday CRM
Activity (Meeting)
1:1Proton Calendar events include title, description, location, start and end time, reminders, attendees, and recurrence rules. We extract event data via Proton Calendar API, preserving timezone information, then create Monday.com Activity records with Activity Type set to Meeting. Note that Proton's encrypted event details require client-side decryption at extraction time; the full event description migrates as the Activity description field. Attendees are mapped to Monday.com People records by email lookup where matching People exist in the destination.
Proton
Drive file and folder
monday CRM
File attachment (via integration)
lossyProton Drive files and folder structures migrate as binary extracts with their original hierarchy preserved. Files attach to the corresponding Monday.com People or Organization record via Monday.com's native file storage (Pro plan and above includes 250 GB). Files that represent deal documents or proposals are flagged for manual attachment to the relevant Monday.com Deal after migration. Proton's end-to-end encryption requires decryption before extraction; we require confirmed key availability before initiating the Drive export.
Proton
User account
monday CRM
Team Member
1:1Proton for Business organizes users into teams with roles. We extract user accounts, role assignments, and team membership from Proton and map them to Monday.com Team Members. The Monday.com CRM seat is provisioned per team member, with the owner role corresponding to Monday.com admin status. Monday.com requires a minimum of 3 seats; we flag any Proton accounts with fewer than 3 users for clarification during discovery.
Proton
Email address (user account)
monday CRM
People email column
1:1Each Proton paid plan supports multiple encrypted email addresses per user. We extract all email addresses within scope and map the primary address to the Monday.com People email column. Additional Proton addresses map to a secondary email column on the People record. Aliases and hide-my-email addresses are noted in a separate text field as they do not map to a native Monday.com CRM equivalent.
Proton
Label and folder
monday CRM
Tags and Groups
lossyProton Mail uses both hierarchical folders and tag-style labels with color coding. We preserve the full label taxonomy and folder hierarchy as a separate tagging layer. Folders with more than 3 levels are flattened into a tag path (e.g., Work/Clients/Acme becomes tag: Work > Clients > Acme) to avoid Monday.com's single-level group structure. Labels migrate as Monday.com tags, and folder path names migrate as Group names on the CRM boards.
Proton
Custom email domain
monday CRM
Workspace domain (read-only reference)
lossyProton Workspace supports up to 15 custom email domains on Standard and 20 on Premium. We extract domain configuration and DNS records and map them to a written domain-verification checklist for the customer's DNS registrar. The domain remains functional during migration; DNS routing updates are coordinated as a separate workstream to avoid mid-migration email disruption. Custom domains themselves do not create CRM records in Monday.com but are noted as part of the email mapping scope.
Proton
Shared link
monday CRM
Not migrated
lossyProton Drive generates shareable links with optional password protection and expiration. These links point to Proton infrastructure and become invalid once data migrates out of Proton. We preserve the original link URLs and access settings in a written reference document so that the customer can manually recreate sharing in their new platform. This is a documentation-only migration for shared links, not a functional transfer.
Proton
VPN configuration and password vault
monday CRM
Not migrated
lossyProton VPN configuration profiles and Proton Pass vault entries do not have CRM equivalents in Monday.com and are outside scope. VPN tunnel configurations are platform-specific and tied to Proton infrastructure; they cannot be meaningfully mapped to other VPN providers or monday.com. Password vault entries are extracted in structured format for the customer's records but are not imported into Monday.com CRM.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Proton gotchas
Storage quota enforcement blocks all write operations at limit
End-to-end encryption keys must be available at extraction time
Mail Professional plan deprecated — no new sign-ups, migration requires plan upgrade
Large mailbox migration via Easy Switch is slow and non-streaming
Custom domain DNS migration requires manual re-verification
monday CRM gotchas
Subitems are not included in bulk exports
Daily API call limits vary sharply by plan
Legacy automations (Sentence Builder) are being deprecated
Excel and account exports only include table views
Enterprise admins can disable non-admin exports
Pair-specific challenges
Migration approach
Discovery and data audit
We audit the source Proton account across all services in scope: Contacts (vCard export with all fields), Calendar events (Proton Calendar API extraction with attendee and recurrence data), Drive files (binary extract with folder hierarchy), and email domain configuration. We also confirm end-to-end encryption key availability and account recovery status. The discovery output is a written data inventory with record counts, storage footprint, and a confirmed migration scope that excludes VPN, password vault, and automation objects upfront.
Destination schema design in Monday.com CRM
We design the Monday.com CRM board structure based on the customer's sales process. This includes configuring People and Organization columns (email, phone, company, tags), creating Deals boards with the appropriate stage values, and setting up Activity logging columns. We pre-create any custom columns needed to preserve Proton field values that lack a native Monday.com equivalent, and we configure tag taxonomy to match Proton's label hierarchy before any data is imported.
Data extraction with key availability check
We extract Proton Contacts in vCard format using Proton's export functionality, decrypting client-side as needed. Calendar events are pulled via the Proton Calendar API with timezone and recurrence preservation. Drive files are extracted as binary downloads with folder structure mapped to a flat manifest. We validate the extraction against the discovery record counts before proceeding to transformation. If any decryption step fails due to lost keys, we halt extraction and escalate to the customer before continuing.
Data transformation and field mapping
We transform extracted data into Monday.com CRM import format. Contacts map to People records with email, phone, address, company, and tags. Calendar events map to Meeting activity records with title, description, time, location, and attendees resolved to People lookups. Organizations are created from company affiliations. Drive files are staged for attachment to the relevant People or Organization record in Monday.com. We run a pre-import validation pass to catch missing required fields and duplicate email addresses before loading begins.
Sandbox validation and reconciliation
We run a full migration into a Monday.com Sandbox or parallel workspace using production-like data volume. The customer's team lead reconciles record counts (People in, Organizations in, Activities in), spot-checks 20-30 records against the Proton source, and confirms the tag taxonomy and column layout before production cutover. Mapping corrections identified during sandbox validation are applied to the production migration plan before go-live.
Production migration and cutover
We run the production migration in record-dependency order: Organizations first, then People with Organization lookups resolved, then Calendar activities as Meetings. Drive files are attached to the relevant People and Organization records. We freeze Proton writes during the cutover window, run a final delta pass for any records modified during migration, then hand off the Monday.com workspace as the system of record. We deliver the automation inventory document for the customer's admin to rebuild in Monday.com's automation center. We support a 5-business-day hypercare window for reconciliation issues reported in the first week of live use.
