Bulk editing tools save significant time, making list hygiene and organization a seamless process for more effective, targeted campaigns.
Reliable Delivery & Core Analytics
Built on Amazon's Simple Email Service (SES), Parlo provides enterprise-level deliverability, ensuring your carefully crafted newsletters reliably land in the primary inbox, not the spam folder.

Parlo FAQ
How does Parlo's pricing work compared to other tools?
Parlo uses a revolutionary usage-based model. You pay for the number of emails you send each month, not for the number of subscribers on your list.

This provides the flexibility to send large campaigns or time-sensitive broadcasts whenever you need to, without being throttled by the platform, ensuring your communications go out on your schedule.

Absolutely. Parlo provides a library of professionally designed, mobile-responsive templates.
