BYOMailer vs BigMailer
BigMailer is strong for agencies managing many client brands from one console. BYOMailer is SaaS-founder-first and lifecycle-first, with full sequences, flat pricing on your own AWS SES, and migration help included.
You should think about switching from BigMailer to BYOMailer if you're a SaaS founder or team who wants a focused, lifecycle-first email platform on your own AWS SES, rather than an agency multi-brand console. BYOMailer fits when email drives activation, retention, and upgrades, you want full lifecycle sequences and flat pricing, and you'd rather have hands-on migration help than move brands and contacts yourself.
Don't switch to BYOMailer if you're an agency whose core job is managing dozens of client brands from a single console. BigMailer is purpose-built for multi-brand agency sending, and that breadth is genuinely its home turf. BYOMailer supports multiple brands on its Portfolio plan, but it's designed lifecycle-first for a SaaS founder or team, not as an agency console.
Moving from BigMailer to BYOMailer usually means exporting your contacts, preserving tags and lists where the export allows, recreating your core templates, rebuilding your most important campaigns as full lifecycle sequences, and connecting your AWS SES account for sending. Both tools already send through your SES, so the sending setup carries over. If you run more than one brand, BYOMailer supports that on its Portfolio plan. We help you make the move on every plan, not just the pricey ones.

They overlap (both send through your own Amazon SES account), but they target different users. BigMailer is built for agencies managing many client brands from one console. BYOMailer is SaaS-founder-first and lifecycle-first, focused on a single team owning its own onboarding, retention, and upgrade email.
Yes. BigMailer and BYOMailer both send through your own AWS SES account, so you keep the low SES sending cost and own your sender reputation. The difference is the product on top: an agency multi-brand console versus a SaaS lifecycle email platform.
Yes. BYOMailer supports multiple brands on its Portfolio plan. That said, if managing dozens of client brands from one console is your core job, BigMailer is purpose-built for that and it's the honest pick. BYOMailer is designed lifecycle-first for a SaaS founder or team who may also run a few brands.

For a SaaS founder or team owning their own lifecycle email, BYOMailer is the closer fit: flat pricing, your own SES, full lifecycle sequences, and migration help. For an agency running many client brands from one console, BigMailer is purpose-built and usually the better choice.
