Instead of Folderly
Folderly alternatives
Folderly combines campaign drafting with email deliverability checks for B2B teams. Its tools can turn an offer, audience, and goal into a campaign draft, test inbox placement and sending signals before a campaign, and monitor placement with alerts over time. The suite also covers DMARC reports, DNS and IP inspection, HTML previews, and real-message testing through API and web access. Free options include two Inbox Insights tests per month and Pulse real-time alerts. Paid mailbox plans start at $96 per month when billed yearly and require a minimum commitment.

An alternative may fit better when you need deeper authentication administration, campaign automation, broader mailbox testing, or a lower paid starting price. Compare whether you need DNS changes and rollback, forensic DMARC details, spam-filter checks, marketing analytics, or blocklist monitoring. Also weigh free-plan limits, billing terms, integrations, platform coverage, and whether a product focuses on Outlook.com reputation or supports wider infrastructure. Before switching, confirm that the specific plan includes the monitoring, testing, sending, and API functions your workflow requires.
