Every comparison page starts with what the other product does better, because a comparison that does not is an advertisement. The price calculator includes the vendors that are cheaper than us.
Outsend and Mailchimp
Mailchimp taught a generation of small businesses how to send email, and it is still the fastest way to build a campaign that looks right without hiring anyone. The differences worth your time are about how you are billed, and whether a newsletter unsubscribe can stop an invoice arriving.
Read the comparisonOutsend and Resend
Resend built the best developer experience in transactional email and earned the audience it has. The reasons to choose Outsend are specific, and they are not about polish.
Read the comparisonOutsend and Postmark
Postmark has been operating carefully since 2010 and has the deliverability reputation to show for it. We agree with most of their design decisions — including the ones we copied.
Read the comparisonOutsend and Amazon SES
This is the least adversarial comparison on the site, because Outsend sends through SES. The question is not which provider — it is whether you want to build the control plane yourself.
Read the comparisonOutsend and Mailgun
Mailgun has been running transactional email at scale since 2010 and has the deliverability experience that comes with it. The differences worth your time are about who owns the sending account, and how much of the provider's answer you get to keep.
Read the comparisonOutsend and SendGrid
SendGrid is the incumbent, and incumbency is a real feature: it works, it scales, and everyone has integrated it before. The differences that matter are about evidence and ownership.
Read the comparisonOutsend and useSend
useSend and Outsend both send through Amazon SES. useSend gives you the code and lets you run it yourself. Outsend is hosted only, and is built around the evidence behind every send.
Read the comparisonOutsend and Plunk
Plunk is an open-source email platform with transactional mail, campaigns, and visual workflow automation in one place. Outsend is narrower, and goes deeper on the evidence behind each send.
