BYOMailer vs Kit (ConvertKit)
Kit gives you unlimited sends, but the Creator plan costs more than your entire email infrastructure should. At 25K subscribers you're already paying $199/mo. With BYOMailer you'd pay $109 and still send as many emails as you want.

Kit uses shared IPs for everyone. One bad sender's spam problem becomes your deliverability problem. With SES, your reputation is entirely yours.
Kit auto-upgrades you to a higher pricing tier the moment you cross a threshold. No warning, no choice. With SES there are no tiers to bump into.

If you're a SaaS founder running lifecycle email (onboarding, product updates, retention, upgrades) and you're watching Kit's Creator plan climb with every new subscriber, it's worth a look. BYOMailer fits when email is tied to activation and revenue rather than creator monetization, and you'd rather your own AWS SES account be the sending infrastructure with flat pricing.
Don't switch to BYOMailer if you're a creator who sells paid newsletters, courses, downloads, or creator products, or who leans on Kit's creator publishing workflow, monetization, or network features. BYOMailer isn't a creator monetization platform, and we're not going to pretend it is.
Moving from Kit to BYOMailer usually means exporting your subscribers, preserving tags where possible (Kit is tag-based, with no lists), recreating your core templates, rebuilding your most important sequences, and connecting your AWS SES account for sending. We help you make the move on every plan, not just the pricey ones.

For SaaS lifecycle email, yes. BYOMailer is built for onboarding, product updates, retention, and upgrade emails tied to activation and revenue. It isn't a creator publishing tool, so it fits product teams a lot better than it fits creators.
Yes. You export your Kit subscribers and import them into BYOMailer, mapping custom fields during import. Kit is tag-based with no lists, so tags are preserved wherever the export includes them. And we help you make the move on every plan, not just the pricey ones.
Yes. BYOMailer has sequences and automations for onboarding, lifecycle, and reactivation. You'll rebuild your most important Kit sequences in BYOMailer during migration, and we'll help.
No, and we're honest about that. BYOMailer isn't a creator monetization suite. It doesn't sell paid newsletters, courses, or downloads, and it doesn't run a creator network. If monetization is core to your business, Kit is genuinely the better fit.
Kit's Creator plan price keeps climbing as your subscriber count grows. BYOMailer charges a flat plan fee and you pay AWS SES directly for sending, so your cost tracks sending volume rather than list size. For a large, growing SaaS list, that's usually the cheaper path.
