Can It Send?

The pricing model seems fair for developers needing programmatic access. The free tier offers 100 API audits monthly, which is sufficient for small projects. For larger operations, the Agency plan at seventy-nine dollars provides twenty-five thousand checks. The inclusion of bulk endpoints and retryable alerts adds practical value. It is unclear if higher tiers offer better rate limits or just higher volume. The fact that every plan runs the same engine suggests consistent quality across price points. This transparency helps in budgeting for email infrastructure audits without hidden costs or surprise fees.

The platform addresses two critical questions for email developers: can the domain send properly, and should we send to the address? The technical depth is impressive, particularly regarding the SPF RFC 7208 parsing. Many tools incorrectly count MX lookups, leading to false positives, but Can It Send correctly identifies that mx costs exactly one lookup. This prevents healthy records from being flagged as broken. The DMARC analysis includes subdomain policies and reporting requirements, which are essential for modern bulk sending. Additionally, the address validation component checks for syntax errors, disposable inboxes, and role accounts, which adds significant value. However, users should be aware that the tool does not perform SMTP probes on port 25 to verify if a specific mailbox actually exists. This deliberate omission means it focuses on what DNS can prove rather than exhaustive verification. The pricing structure is transparent, with a free tier for browser checking and clear API limits. The distinction between authentication and verification is clearly maintained, preventing confusion. For developers managing multiple domains, the ability to monitor domains and receive retryable alerts justifies the cost. The tool effectively helps avoid the five thousand daily limit cliff where Gmail and Yahoo reject unauthenticated mail. Overall, it provides a comprehensive solution for ensuring email deliverability through proper DNS configuration.

While the DNS auditing is precise, the limitation of not detecting catch-all addresses or verifying actual mailbox existence is a notable gap. For bulk senders, this means you might still face delivery issues despite passing the DNS checks, requiring additional verification steps.

The specific handling of the mx lookup cost as a single unit rather than per host resolves common confusion. This precision makes the tool reliable for accurate auditing of complex DNS records.

From the information available, Can It Send offers a distinct separation between domain authentication and address validation. The explanation of the SPF lookup limit being misunderstood by other tools is reassuring for developers who have faced false alarms. However, the fact that they do not probe for actual mailbox existence means it is not a complete verification solution on its own. It serves as a solid tool for DNS health checks.
