Keep SocketLabs, or make your own?
Keep it
To replace SocketLabs you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 17 of the 26 other email sending services grade higher. It costs $479.40 a year.
What you could make
- Reports: an app builder makes this well.
What you could not
- Mail servers with a good name among inbox providers.
- It plugs into other products, SendGrid, Mailgun and Bird among them, and has an API.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. SocketLabs’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
