Frequently Asked Questions

Changeflow FAQ

How does Changeflow differ from traditional website monitoring tools?

Traditional tools typically alert you that something on a page has changed, often requiring you to manually compare screenshots or text to find the relevant update. Changeflow uses AI to read and understand the page content in context. It filters out insignificant changes (like ad rotations or date stamps) and provides a plain-English summary of only the meaningful updates, saving you considerable time and effort.

Can Changeflow monitor websites that require a login?

Yes. Changeflow's advanced anti-blocking technology is designed to handle complex access scenarios, including sites behind login walls. Its high success rate on pages other tools cannot reach makes it ideal for monitoring private portals, subscription-based news sites, or internal dashboards where critical information is updated.

How do I set up monitoring for a new website or topic?

Setup is designed to be simple and non-technical. You provide the starting URL and a brief description in plain English of what you care about (e.g., "track changes to product specifications and pricing on this laptop model page"). Changeflow's AI agent interprets your instructions and begins monitoring. You can also use the chatbot to add multiple pages quickly.

What happens if I need to monitor hundreds of pages?

Changeflow scales efficiently. The "Smart Link Following" feature can turn a single directory or news page into a comprehensive feed by following and evaluating new links. For large-scale onboarding, Business and Enterprise plans offer bulk import capabilities from CSV/Excel files or via site crawls, allowing you to monitor thousands of sources seamlessly.

Parlo FAQ

Is there a free trial available?

Yes, Parlo offers a completely free trial to get you started. Your first month is 100% free, and no credit card is required to sign up. This allows you to fully explore the platform's features, import your contacts, and send test campaigns to see if Parlo is the right fit for your needs before any financial commitment.

How does the usage-based pricing work?

Parlo operates on a flexible, usage-based pricing model. You choose a plan (like the Starter or Business plan) which includes a certain number of contacts and a monthly email sending limit. You only pay for the plan you select, and you can switch plans at any time. This means your costs scale directly with your usage, preventing you from overpaying for capacity you don't need.

Can I import my existing email list?

Absolutely. Parlo makes it simple to import your existing contacts. You can upload a CSV file directly into the platform for a quick and seamless setup. The system also supports adding custom attributes during import, so you can bring over segmented data and continue targeted marketing from day one.

How does Parlo ensure good email deliverability?

Parlo ensures high deliverability rates by integrating with Amazon SES (Simple Email Service), a trusted and robust email-sending infrastructure used by large enterprises. This partnership means your emails are sent via a reliable service with strong sender reputations, significantly increasing the chance they land in your subscribers' primary inbox instead of being marked as spam.
