About MailerSend Status Monitoring

IsDown has maintained continuous monitoring of MailerSend, a Email Delivery solution, since January 2023. Our database contains 21 documented incidents from the past 3 years, giving us deep insight into MailerSend's reliability patterns and typical resolution times. We parse MailerSend's official status page across all 5 components, interpreting statuses like operational, degraded performance, partial outage, and major outage to deliver precise uptime metrics and targeted notifications.

When MailerSend experiences issues, you need accurate information fast. IsDown combines official status page data with user-reported issues, giving you early detection when vendors are slow to acknowledge problems, plus verified incident details once they do. You get affected components, severity levels, and real-time resolution updates from both sources.

Engineering and operations teams rely on IsDown to monitor MailerSend and receive verified outage alerts. Get instant notifications through Slack, Teams, PagerDuty, or 20+ other integrations.

How IsDown monitors MailerSend?

IsDown monitors MailerSend health in almost real-time

Every few minutes we check the status page of MailerSend (and 5,420+ other services) for issues. We collect the status and outage information across all 5 MailerSend components. We also monitor user reports alongside official sources. Since vendors often take time to report incidents, monitoring user reports helps us alert you early.

The moment an issue is detected in MailerSend, IsDown sends an alert and updates your status page

Not only will you get notified, but IsDown offers notification filters so you can choose which issues you want to be alerted about. This way you avoid getting all incidents from MailerSend and other services, focusing only on those affecting your business.

One status page to monitor all your external dependencies

What you get when monitoring MailerSend with IsDown

Track MailerSend incidents and downtimes by severity

IsDown checks MailerSend official status page for major/minor outages or downtimes. A major outage is when MailerSend experiences a critical issue that severely affects one or more services/regions. A minor incident is when MailerSend experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. The moment we detect a MailerSend outage, we send you an alert and update your dashboard and status page.

Get alerted as soon as users report problems with MailerSend

MailerSend and other vendors don't always report outages on time. IsDown collects user reports to provide early detection of outages. This way, even without an official status update, you can stay ahead of possible problems.

All the details of MailerSend outages and downtimes

IsDown collects all information from the outages published in MailerSend status page to provide the context of the outage. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.

Prepare for upcoming MailerSend maintenance events

MailerSend publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.

Only get alerted on the MailerSend outages that impact your business

IsDown monitors MailerSend and all their 5 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about. For example, you can choose which components or regions affect your business and filter out all other outages. This way you avoid alert fatigue in your team.
