Active Monitor: Admins can view all currently running campaigns across the entire platform to ensure system stability and compliance.

Powerful Email List Management

Organize your audience with precision and scale your database without the complexity.

Effective marketing starts with a clean, well-organized database. Our Email List Management system provides the tools to categorize your subscribers, capture new leads, and maintain data integrity, all while allowing you to monetize growth through plan-based limitations.

Flexible List Organization

Comprehensive List Control: Create and manage multiple lists for different brands, departments, or interest groups. Each list acts as a dedicated environment for your subscriber data.
Smart Segmentation: Don’t just send—target. Use advanced segmentation support to filter your lists based on subscriber behavior, custom fields, or join dates, ensuring your content is always hyper-relevant.
Seamless Import/Export: Migrating from another platform? Use our robust import tools to bring in your existing contacts via CSV or Excel. Need your data locally? Export any list or segment with a single click.

Plan-Based Scaling (Monetization)

Control your platform’s resources and encourage upgrades by setting granular limits for each subscription tier:

Max Number of Lists: Define how many unique lists a user can maintain (e.g., 3 for Basic, Unlimited for Pro).
Max Subscribers Per List: Limit the capacity of individual lists to manage server load and pricing tiers.
Max Forms Per List: Control how many lead-capture forms a user can generate to grow their database.

️ Growth Tools

Custom Subscription Forms: Design and embed signup forms directly into your website to capture leads automatically.
Data Hygiene: Built-in tools help you identify inactive subscribers and maintain high deliverability by keeping your lists fresh and engaged.

Sending Domains & Deliverability Trust

Establish sender authority and ensure your emails land in the inbox, not the spam folder.

Professional email marketing requires authenticated infrastructure. Our Sending Domains module provides users with the tools to verify their own domains, boosting brand credibility and deliverability rates through industry-standard protocols.

️ Domain Management & Authentication

Add Custom Sending Domains: Allow users to send emails from their own professional domains (e.g., hello@yourbrand.com) rather than generic shared addresses.
DKIM + SPF Setup: Automatically generate the required DomainKeys Identified Mail (DKIM) and Sender Policy Framework (SPF) records to authenticate outgoing mail and satisfy strict ISP requirements.
Intuitive DNS Validation UI: A user-friendly interface that shows the exact DNS records needed. It features real-time status checks to confirm when a domain is correctly verified and ready for use.

Admin Policy & Access Control

Strict Verification Toggle: Global “Requirement” toggle—decide whether users must verify a domain before they are permitted to send any campaigns.
Plan-Based Domain Limits: Control your infrastructure load by limiting the number of verified sending domains a user can attach based on their subscription tier (e.g., 1 domain for Basic, 10 for Enterprise).
Permission-Based Access: Enable or disable the “Custom Domain” feature entirely for specific user groups or lower-tier plans.

️ Reputation Protection

By empowering users to use their own domains, you isolate sender reputations, ensuring that the sending habits of one user do not negatively impact the deliverability of others on your platform.

Professional Tracking Domains

Whitelabel your links and improve deliverability by masking tracking URLs with your own brand.

Standard tracking links often use shared domains that can be flagged by spam filters. By utilizing Tracking Domains, you replace generic system links with your own branded URLs, ensuring a cohesive brand experience and significantly higher inbox placement rates.

Branded Link Management

Custom Tracking URLs: Allow users to add their own domains or subdomains (e.g., links.yourbrand.com) to handle all click-through and open-tracking redirects.
CNAME Verification: A streamlined setup process that guides users through pointing their DNS CNAME records to your platform, with built-in validation to ensure the connection is active.
Analytics Tracking Enabled: Once verified, the system automatically rewrites all campaign links to use the custom domain while continuing to feed detailed engagement data back to the dashboard.

Flexible Compliance & Controls

Mandatory Setup Toggle: Admins can choose to make Tracking Domains optional or a Requirement (Must Add: Yes/No) before a user is allowed to send campaigns.
Plan-Based Limitations: Scalable access that lets you limit the number of tracking domains a user can register based on their specific subscription plan.
Access Control: Restrict this advanced deliverability feature to premium tiers, providing a compelling reason for users to upgrade.

Deliverability & Trust

Avoid Link Shilling> Using a dedicated tracking domain prevents your emails from being associated with the link-clicking reputation of other senders.
Consistency: When a subscriber hovers over a link, seeing your brand name instead of a cryptic third-party URL builds trust and increases Click-Through Rates (CTR).

Enterprise-Grade Delivery System

Total control over your mail flow with precision routing and automated reputation management.

The core of any email platform is its ability to deliver. Our advanced Delivery System module provides the infrastructure to manage multiple sending routes, enforce strict quotas, and maintain high sender scores through automated bounce and complaint processing.

Versatile Delivery Servers

Custom SMTP Support: Connect to any external provider like Amazon SES, SendGrid, Mailgun, or your own private PowerMTA server with ease.
Multiple SMTP Profiles: Create and manage a library of delivery configurations. Use different servers for different types of traffic (e.g., transactional vs. marketing).
Intelligent Assignment: Admins can assign specific delivery servers to individual customers or entire subscription plans, ensuring your “VIP” users always have the best routes.

️ Sending Quota & Throttle Control

Protect your infrastructure and stay within provider limits with granular rate-limiting tools:

Flexible Quota Enforcement: Set hard limits on how many emails a user can send on a Daily, Weekly, or Monthly basis.
Precision Throttling: Control the speed of delivery with Per Minute or Per Hour sending caps to prevent sudden spikes from triggering spam filters.

Reputation & Feedback Loops

Automated Bounce Handling: The system automatically detects permanent (Hard) and temporary (Soft) bounces, cleaning your lists instantly to keep your bounce rate low.
Complaint Handling: Integrated Feedback Loop (FBL) support automatically unsubscribes users who mark your email as spam, protecting your sender reputation across major ISPs.
Automatic Blacklist Monitoring: Ensure your delivery servers are always in good standing and get notified if a server’s reputation is at risk.

Intelligent Bounce Servers

Maintain a pristine sender reputation with automated list cleaning and advanced bounce processing.

A high bounce rate is the fastest way to get blacklisted. Our Bounce Server module automates the “dirty work” of list hygiene by monitoring dedicated mailboxes and instantly acting on delivery failures before they damage your reputation.

Professional Bounce Monitoring

Universal IMAP/POP Support: Effortlessly connect to any mail server using standard IMAP or POP3 protocols to monitor “Return-Path” addresses for non-delivery reports.
Flexible Assignment: Assign specific bounce servers to individual Customers or Email Lists. This allows for total isolation of delivery data between different clients or brands.
Real-Time List Cleaning: Once a bounce is detected, the system immediately updates the subscriber’s status, ensuring they are not included in future mailings.

Automatic Bounce Classification

Not all bounces are created equal. Our system intelligently categorizes failures to help you make informed decisions:

Hard Bounce Detection: Automatically identifies permanent errors (like “email address does not exist”) and blacklists the address immediately.
Soft Bounce Management: Tracks temporary issues (like “mailbox full”) and allows for a configurable number of retries before marking the address as inactive.
Smart Error Parsing: Analyzes raw SMTP response codes to provide clear, human-readable reasons for every failed delivery attempt.

️ Reputation Safeguards

Automated Suppression: Prevents the “retrying” of known bad addresses, which is a key signal used by ISPs like Gmail and Outlook to identify spammers.
Bounce Dashboard: View detailed logs and percentages to monitor the health of your data sources and the quality of your lead generation.

Robust Monetization & Billing

Turn your platform into a revenue-generating powerhouse with a fully automated billing ecosystem.

Scaling a SaaS business requires more than just great features; it requires a seamless financial engine. Our billing system automates the entire customer lifecycle—from the first subscription to recurring renewals and tax-compliant invoicing—so you can focus on growth while the platform handles the transactions.

Dynamic Subscription Plans

Granular Feature Access Control: Create multiple tiers (e.g., Starter, Pro, Agency) and toggle specific high-value features like A/B testing or automation workflows based on the plan.
Smart Limits Enforcement: Hard-code limits for subscribers, daily sending volume, and total campaigns. The system automatically prevents overages, providing a natural incentive for users to upgrade.
Promotional Coupon Support: Drive sales with flexible discount codes. Create percentage-based or fixed-amount coupons for seasonal promotions or “early bird” sign-ups.

Automated Financial Operations

Integrated Invoices System: Professionally branded PDF invoices are generated automatically for every transaction, keeping your users informed and your bookkeeping organized.
Global VAT / TAX Support: Stay compliant worldwide. The system handles tax calculations based on the user’s location, ensuring the correct VAT or sales tax is applied during checkout.
Seamless Payment Methods: Native integration with leading gateways like Stripe, PayPal, and more, supporting secure credit card processing and recurring billing cycles.

Lifecycle & Subscription Management

Automatic Upgrades & Downgrades: Users can change plans instantly. The system calculates pro-rated amounts and adjusts feature access in real-time without manual intervention.
Grace Period Handling: Retain customers even when payments fail. Set custom grace periods that allow users limited access while the system automatically retries their payment method.
Automated Suspension: If a subscription remains unpaid past the grace period, the system securely restricts access until the account is settled.
