Resend
Resend — Best for an early-stage developer team that prioritizes an excellent modern API and fast implementation; it encourages authenticated subdomains and SPF/DKIM/DMARC, but I would not select it over the leaders for a mature, complex deliverability program.

SMTP2GO
SMTP2GO — A strong, practical SMTP relay choice for applications, devices, and businesses that value simple setup and responsive support; use a dedicated IP only once you have steady sufficient volume to establish its reputation.
