Feature Comparison
Adswize
Automated Daily Performance Analysis
This core feature executes a scheduled, comprehensive diagnostic of all connected Meta ad accounts. The AI engine analyzes key performance indicators (KPIs) including Cost Per Acquisition (CPA), Return on Ad Spend (ROAS), Click-Through Rate (CTR), and conversion data across campaigns, ad sets, and individual creatives. It processes this data against historical performance over user-selected periods (7, 14, or 30 days) to identify statistically significant trends, anomalies, and performance deltas, eliminating the need for manual data aggregation and cross-tabulation.
Actionable Optimization Recommendations
Based on its diagnostic analysis, the platform generates a prioritized list of concrete optimization actions. These are presented as clear, executable tasks within a daily checklist (e.g., "Pause Ad Set 'Summer Sale' - CPA increased by 52%", "Increase budget for 'Lookalike FR' - ROAS at 4.2x"). Each recommendation is data-backed, specifying the exact asset, the metric driving the suggestion, and the proposed action, thereby replacing guesswork with algorithmic decision-making for budget shifts, ad pauses, and scaling initiatives.
Interactive AI Insights Assistant
Beyond automated reports, Adswize includes a conversational AI interface that allows users to query their campaign data using natural language. Users can ask specific, contextual questions such as "Which audience segment has the lowest CPA this week?" or "Why did my ROAS drop on Thursday?" The assistant parses the query, accesses the underlying performance database, and provides an instant, plain-English explanation with supporting data points, functioning as an on-demand analytics expert.
Consolidated Performance Dashboard
The platform provides a unified visual dashboard that distills complex campaign data into key, actionable metrics. It offers an at-a-glance view of overall account health, daily progress on recommended actions, and highlights of top-performing and underperforming assets. This dashboard is designed for clarity, surfacing only the most critical insights needed for daily decision-making, thereby reducing time spent navigating native platform interfaces.
Email List Cleaner
Client-Side Privacy-First Validation
The entire email validation process is engineered to occur within your web browser. The only data transmitted externally are domain names, which are sent to Google's DNS service to verify MX records for mail server configuration. The actual email addresses you input are never sent to or stored on any external server, ensuring complete data sovereignty and privacy. This architecture is fully transparent and verifiable through the project's open-source code.
Comprehensive Email Address Verification
The tool performs a multi-layered validation check on each email address. This includes a rigorous syntax check to ensure the address conforms to RFC standards and a domain verification step that confirms the domain exists and is configured to accept email (via MX record lookup). While it cannot guarantee an inbox exists, it identifies addresses that are definitively invalid due to malformed syntax or non-existent domains.
Advanced Filtering and Sanitization Options
Beyond basic validation, Email List Cleaner provides granular control over list sanitization. Users can configure options to allow or flag disposable email addresses, role-based addresses (e.g., info@, sales@), and duplicate entries. The duplicate detection is sophisticated, accounting for provider-specific behaviors like Gmail ignoring dots in the local part and supporting email address tags (e.g., [email protected]).
Support for Complex Email Formats
The system accepts input in multiple common formats, providing flexibility for users. You can paste a simple list of email addresses (one per line) or use the "Name [email protected]" format. This capability ensures that lists exported from various CRM systems, marketing platforms, or contact managers can be processed directly without requiring manual reformatting beforehand.

Email List Cleaner
Improving Email Marketing Campaign Deliverability
Marketers and small business owners can use the tool to sanitize their mailing lists before launching campaigns. By removing invalid addresses, disposable emails, and duplicates, they significantly reduce bounce rates, protect their sender reputation with ISPs, and improve overall deliverability metrics, ensuring their messages reach genuine, engaged subscribers.
Pre-Migration Data Cleansing for System Administrators
When migrating user databases between platforms (e.g., CRM, helpdesk, or communication systems), administrators can utilize Email List Cleaner to validate and clean the exported email list.

Filtering out role-based addresses and unlikely valid addresses (e.g., [email protected]) helps focus communication on individual recipients, potentially improving open rates and ensuring compliance with best practices for consent-based communication.
Overview
About Adswize
Adswize is a specialized AI-powered software platform engineered to automate and optimize Meta advertising campaigns. It functions as an intelligent assistant for advertisers, media buyers, agencies, and brands, directly addressing the critical challenge of data overload and inefficient manual analysis. The platform connects via API to users' Meta Ads Manager accounts, where it performs automated, daily analysis of campaign performance across configurable timeframes (7, 14, or 30 days). Its core operational mechanism involves transforming complex, raw performance metrics into structured, actionable intelligence. Instead of presenting spreadsheets of numbers, Adswize generates concise daily summaries that pinpoint high-performing assets, identify underperforming elements, and highlight budgetary inefficiencies. The system's AI then delivers specific, prioritized optimization recommendations—such as pausing specific ads, reallocating budget between ad sets, or refreshing creatives—enabling users to execute data-driven decisions rapidly. The primary value proposition is a significant reduction in the time and cognitive load required for daily campaign management, directly translating to decreased ad spend waste and improved return on advertising spend (ROAS) through systematic, AI-guided scaling of successful campaign components.

Frequently Asked Questions
Adswize FAQ
How does Adswize connect to my Meta Ads account?
Adswize establishes a secure, read-only connection to your Meta Ads account using Meta's official OAuth API protocol. This connection is permission-based, requiring you to log in and grant explicit access. The platform only retrieves performance data and cannot make changes to your account without your explicit approval for each recommended action, ensuring you maintain full control over all campaign modifications.
What specific data points does the AI analyze for its recommendations?
The AI algorithm analyzes a comprehensive set of Meta Ads performance metrics. Primary inputs include Cost Per Result (CPA/CPC), Return on Ad Spend (ROAS), Conversion Rate, Click-Through Rate (CTR), Impression share, frequency, and spend data. It correlates these metrics across campaigns, ad sets, and ads, comparing them against historical benchmarks (7, 14, 30-day windows) to identify significant positive or negative trends that warrant optimization actions.
Can I customize the time period for the AI's analysis?
Yes, Adswize provides configurable analysis windows. Users can set the primary lookback period for the AI's daily diagnostic to 7, 14, or 30 days. This allows for tailoring the analysis to match different campaign cycles and business models; for example, a fast-paced e-commerce brand might use a 7-day window for agility, while a brand with longer consideration cycles may opt for a 30-day view for more stable trend analysis.
Is my advertising data secure with Adswize?
Adswize employs enterprise-grade security measures. The connection to Meta is encrypted and read-only. All data transmitted and stored is encrypted in transit and at rest. The platform adheres to strict data privacy standards and does not share or sell user data. You retain ownership of all your advertising data, and you can revoke the platform's access at any time directly through your Meta Business Manager settings.
Email List Cleaner FAQ
How accurate is the email validation?
Email List Cleaner provides highly reliable technical validation. If it marks an address as invalid, it is almost certainly invalid due to incorrect syntax or a domain that does not accept email. However, a "valid" result means the address is correctly formatted and the domain has valid MX records; it cannot guarantee the specific mailbox exists or is active, as that would require sending a message, which is technically impossible for a third-party tool without interaction.
Is my email list data kept private?
Yes, absolutely. The tool is designed with a strict privacy-first principle. All processing occurs locally in your browser. The only data ever transmitted is the domain name (e.g., "example.com") from an email address to Google's public DNS service to check for MX records. Your full email addresses, the list itself, and any associated names are never sent to or stored on any server, including ours.
What does "Allow unlikely valid email addresses" mean?
This option controls the filtering of email addresses that, while technically valid in format and domain, are semantically unlikely to be genuine personal or professional addresses. Examples include "[email protected]" or "[email protected]". Enabling this option will include such addresses in your valid output list, while disabling it will filter them out as invalid, helping you target more probable human recipients.
How does duplicate detection work for services like Gmail?
The duplicate detection feature is aware of specific email provider behaviors. For Gmail, it treats "[email protected]" and "[email protected]" as the same address, as Gmail ignores dots in the local part. It also recognizes email address tags, so "[email protected]" is considered identical to "[email protected]". This ensures truly unique addresses are identified, preventing unnecessary sends to the same inbox.
