Community FAQ

Questions by product

InboxAlly FAQ

Does InboxAlly support self-hosting or is it fully SaaS-only?

InboxAlly is offered exclusively as a SaaS platform and does not support self-hosting. All email deliverability and inbox placement analytics run on their cloud infrastructure, so teams must rely on their hosted environment for operation.

Community insight informed by Reddit discussions

Can InboxAlly be used offline or does it require constant internet connectivity?

InboxAlly requires an active internet connection to function since it processes deliverability data in real-time on its cloud servers. There is no offline mode or local processing capability available.

Community insight informed by Hacker News discussions

What are the data ownership and privacy policies for emails and analytics data stored by InboxAlly?

InboxAlly retains ownership of the platform but customers maintain full ownership of their email content and analytics data. The platform complies with standard data privacy regulations and offers data export options, but data is stored on InboxAlly’s servers under their privacy policy.

Community insight informed by Forums discussions

Are there any API rate limits or feature limitations on InboxAlly’s deliverability analytics API?

InboxAlly enforces API rate limits that vary by subscription tier, with higher tiers allowing more requests per minute. Some advanced features like detailed inbox placement reports and historical data access are gated behind premium plans.

Community insight informed by StackOverflow discussions

What migration or export options does InboxAlly provide for teams switching from Mailgun or other providers?

InboxAlly offers tools to import existing email sending domains and historical deliverability metrics via CSV uploads or API integrations. However, migrating complete historical data may require manual effort depending on the source platform’s export capabilities.

Community insight informed by Reddit discussions

Mailgun FAQ

Can I self-host Mailgun or is it strictly a cloud service?

Mailgun is a fully managed cloud-based email delivery service and does not offer a self-hosted version. All email sending, deliverability monitoring, and validation features run on Mailgun's infrastructure, so you cannot deploy it on-premises or offline.

Community insight informed by Reddit discussions

Does Mailgun provide offline email sending capabilities or queueing if my app loses internet connection?

Mailgun requires an active internet connection to send emails via its API or SMTP. It does not provide offline queueing or local email sending features. You must implement your own local queueing mechanism if you want to handle intermittent connectivity before forwarding emails to Mailgun.

Community insight informed by Hacker News discussions

Who owns the email data and logs when using Mailgun? Can I export or delete all stored data?

Mailgun retains email sending logs and analytics data as part of their service. While you retain ownership of your email content, Mailgun stores metadata and logs on their servers. You can export logs via their API for a limited retention period and request data deletion per their privacy policy, but full raw data export is limited.

Community insight informed by StackOverflow discussions

Are there any API limitations or rate limits I should be aware of when using Mailgun for high-volume sending?

Mailgun enforces rate limits and API usage quotas depending on your plan. Free and lower-tier plans have stricter limits on the number of messages sent per month and API request rates. Higher-tier and enterprise plans offer increased limits and dedicated IPs to support high-volume sending. It's important to review your plan's limits to avoid throttling.

Community insight informed by Forums discussions

What is the recommended process to migrate from another email service to Mailgun without losing deliverability history?

Migrating to Mailgun involves updating your DNS records (SPF, DKIM, DMARC) to authorize Mailgun sending, importing your contact lists, and gradually shifting sending volume to Mailgun. Deliverability history from your previous provider is not transferable, so you should monitor reputation closely and warm up your IPs if using dedicated IPs. Mailgun provides tools to monitor inbox placement to help during migration.
