Parlo FAQ
How does Parlo ensure high email deliverability?
Parlo ensures high deliverability by using Amazon Simple Email Service (SES) as its core sending infrastructure. Amazon SES manages critical aspects like IP reputation, bounce processing, and compliance with major ISPs. This enterprise-grade foundation, combined with Parlo's tools for list hygiene (bounce/unsubscribe alerts), provides a technically superior environment for getting your emails into the primary inbox.
Can I integrate Parlo with my existing application or website?
Yes, Parlo is built as an API-first platform, making integration straightforward for developers. You can use the API to programmatically manage contacts, send transactional or campaign emails, and retrieve analytics data. This allows Parlo to function as a seamless email service layer within your custom application, CRM, or other marketing tools.
What is the difference between the Starter and Business plans?
The Starter plan is designed for lower-volume senders, with a daily sending limit of 300 emails and standard support. The recommended Business plan removes daily sending limits, includes priority support, and allows for the removal of Parlo branding (for an additional fee). Both plans include core features like the drag-and-drop editor, custom attributes, and analytics, but the Business plan is built for scalability and professional use.
How does the usage-based pricing model work?
Parlo charges based on the number of emails you send each month, not the number of contacts you store. You can grow your list infinitely without cost. The Business plan has a monthly base fee that includes a set number of emails (e.g., 5,000), with transparent overage pricing for additional volume. This model aligns cost directly with usage, preventing you from paying for unused capacity.
