Self-hosted email system vs third-party ESP, what’s the better call at this stage
Hey all, looking for some advice here. My customer base has grown to a decent size now, and I’ve been collecting emails through my signup form for a while, but I’ve actually never sent a single marketing/update email to them yet, kind of embarrassing, I know 😅
Now I’m finally ready to start doing real email marketing, and I’m stuck on a decision: should I build my own email sending system, or just go with an established third-party ESP (like Mailchimp, SendGrid, etc.)?
Part of me wants to self-host, mainly because I like the idea of owning all my data and not being dependent on (or losing data to) a third party. But I have a feeling self-hosting email at this stage could open up a can of worms deliverability, IP reputation, spam filters, etc.
For someone still early-ish in scaling email ops, what would you recommend? What are the real tradeoffs between building it myself vs just using a third-party platform for now? Would love to hear from people who’ve been through this decision.
Thanks in advance!
