Aspose.Email for SharePoint vs. Native SharePoint Email: A ComparisonEmail processing and management in SharePoint environments is a common enterprise need: organizations want reliable ingestion, archiving, conversion, and automated workflows for messages and attachments. Two approaches often compared are using SharePoint’s native email capabilities and using a third-party component such as Aspose.Email for SharePoint. This article compares these options across functionality, flexibility, performance, security, administration, and cost to help you choose the right approach for your organization.
Summary comparison (quick take)
- Native SharePoint Email: Built-in, minimal setup, suitable for basic incoming-email-to-list/library scenarios. Limited format support and processing features; may require custom development for complex workflows.
- Aspose.Email for SharePoint: Rich feature set for parsing, converting, searching and automating advanced email workflows; supports many formats and fine-grained processing. Requires installation and licensing but reduces heavy custom development.
What each solution is
Native SharePoint Email
SharePoint (on-premises versions such as 2013/2016/2019 and earlier) includes native support for incoming email for lists and libraries. Administrators enable the incoming email service (often integrated with Exchange or a pickup/drop folder) and configure lists or libraries to accept messages. When an email arrives, SharePoint can store the email body and attachments as list item fields or files in a library.
Strengths:
- No third-party licensing.
- Simple out-of-the-box behavior for storing messages and attachments.
- Tight integration with SharePoint permissions and versioning.
Limitations:
- Limited control over message parsing, metadata extraction, or conversion to other formats.
- Inconsistent support across SharePoint Online (modern Microsoft 365) — many built-in incoming email features are unavailable or limited.
- Minimal capabilities for automated advanced processing (search inside attachments, converting emails to PDFs, extracting structured data).
Aspose.Email for SharePoint
Aspose.Email for SharePoint is an add-on from Aspose that extends SharePoint’s capabilities by adding robust email processing features. It provides server-side components to import, convert, parse, index, and manipulate email messages (formats like EML, MSG, MHT, and MIME), attachments, and headers inside SharePoint. Typical capabilities include converting emails to HTML or PDF, extracting metadata, automated archiving, custom indexing, and APIs for deeper workflow integrations.
Strengths:
- Broad format support (MSG, EML, MHT, PST in related Aspose.Email products).
- Conversion features (email → PDF/HTML/XPS) and advanced attachment handling.
- Programmatic APIs and integration points for custom workflows and indexing.
- Better support for searching within email bodies and attachments after conversion/indexing.
Tradeoffs:
- License cost and additional component installation.
- Requires configuration and possible developer effort to integrate into existing workflows.
Detailed comparison
Feature coverage
- Storage of incoming email:
- Native: Stores email body and attachments into list/library items with minimal processing.
- Aspose.Email: Can store original email formats and also produce converted representations (PDF, HTML), richer metadata, and structured extraction.
- Supported formats:
- Native: Handles standard MIME emails; limited or no built-in support for MSG or specialized formats without extra processing.
- Aspose.Email: Supports MSG, EML, MHT and more, plus advanced handling of multipart messages and embedded objects.
- Conversion and rendering:
- Native: No built-in conversion to PDF/print-friendly formats.
- Aspose.Email: Can convert emails to PDF, HTML, XPS, enabling better archival and previewing.
- Metadata extraction and indexing:
- Native: Basic fields (From, To, Subject, Date); deeper extraction requires custom code or additional services.
- Aspose.Email: Provides APIs to extract headers, recipients, inline images, attachment metadata, and custom properties for indexing.
- Automation and workflow integration:
- Native: Works with SharePoint workflows/Power Automate but often requires custom parsing steps.
- Aspose.Email: Facilitates automation by exposing parsing/conversion APIs usable in workflows or custom SharePoint solutions.
Deployment & platform considerations
- SharePoint on-premises:
- Native incoming email: Requires configuring SharePoint’s incoming email service and integration with Exchange or SMTP pickup/drop folders.
- Aspose.Email: Installs as a SharePoint add-on or integrated via custom code; runs on server with proper permissions.
- SharePoint Online (Microsoft 365):
- Native incoming email features are largely deprecated or limited; use of connectors, mail-enabled lists, or Power Automate is typical.
- Aspose.Email: Third-party components must be compatible with SharePoint Online architecture; typically you’ll use Aspose APIs in a middleware layer (Azure Function, Logic App, or custom service) to process emails before storing results in SharePoint Online.
Security & compliance
- Native SharePoint:
- Inherits SharePoint security model and governance; no extra vendor exposure.
- Data residency and control remain within your SharePoint environment.
- Aspose.Email:
- Introduces third-party binary/code; ensure you validate vendor security posture and compliance.
- On-prem installations keep data internal; cloud or middleware integrations require secure transport and storage planning.
- Aspose as a vendor provides enterprise licensing and support — review compliance statements if you have strict regulatory needs.
Performance & scalability
- Native:
- Performance adequate for light to moderate email volumes; heavy loads might require custom architecture and scaling.
- Aspose.Email:
- Designed to handle larger volumes with optimized parsing and conversion, but throughput depends on how the add-on/service is hosted and resources allocated.
- Conversions (to PDF) and heavy parsing will add CPU and memory load; plan capacity accordingly.
Administration & maintenance
- Native:
- Lower overhead for installations (built into SharePoint) but requires Exchange/SMTP configuration and monitoring of incoming email service.
- Simpler to maintain if requirements are basic.
- Aspose.Email:
- Requires installation, licensing, updates, and occasional troubleshooting of the add-on or middleware.
- Offers richer logging and diagnostic features in many cases, aiding administrators when diagnosing failures in email processing.
Development and customization
- Native:
- Custom features often require Build/Deploy using SharePoint Framework (SPFx), event receivers, or Power Automate flows plus custom parsing libraries.
- Aspose.Email:
- Provides APIs and SDKs that reduce low-level parsing effort; developers can focus on business logic instead of email format handling.
- Example tasks simplified: extract attachments, convert message to PDF, remove EXE attachments automatically, normalize headers into SharePoint metadata.
When to choose Native SharePoint Email
- Your needs are simple: you only need to store incoming emails and attachments in a SharePoint list or library with no advanced parsing or conversion.
- You prefer to avoid third-party licensing and want to keep a pure Microsoft stack.
- You run on-prem SharePoint with a stable Exchange/SMTP setup and modest email volume.
- You want minimal setup and maintenance footprint.
When to choose Aspose.Email for SharePoint
- You need advanced format support (MSG/EML conversions), consistent rendering, or conversion to PDF/HTML for archival or legal purposes.
- You require automated extraction of metadata, detailed indexing, or searchability across email bodies and attachments.
- You must implement complex email workflows (attachment normalization, virus-safe conversions, automated classification) without building low-level parsers yourself.
- You operate at scale and expect significant message volume or varied message formats.
- You need the flexibility to integrate processing in middleware for SharePoint Online scenarios.
Examples / typical use cases
- Legal/archive compliance: Convert all incoming emails to PDF and store with extracted metadata for e-discovery. Aspose.Email simplifies converting and normalizing emails; native SharePoint would require custom code and converters.
- Automated ticketing or CRM ingestion: Parse incoming emails, extract structured fields (like ticket ID), attach to SharePoint lists, and trigger workflows. Aspose.Email reduces parsing complexity.
- File-server migration: Migrate legacy MSG/EML-based archives into SharePoint with format conversion and indexing. Aspose.Email supports specialized formats and batch processing.
- Simple newsletter collection: Mail-enabled library collecting emails from users with attachments—native SharePoint is often sufficient.
Cost considerations
- Native: No additional licensing beyond SharePoint and Exchange/SMTP infrastructure. Potential hidden costs in custom development for advanced features.
- Aspose.Email: Licensing cost for the component plus implementation effort. Usually reduces developer time and long-term maintenance for complex email handling.
