What Loops is
Loops is email for software companies: transactional and marketing sends in one place with a modern API. Keeping product and marketing email in one place with a modern API suits software teams who do not want two systems and two reputations. It is young, so campaign tooling is thinner than the established marketing platforms.
What SendGrid is
SendGrid delivers email at scale through an API or SMTP, with deliverability tooling and analytics. It handles volume reliably and the deliverability tooling is mature, which is why it remains a default at scale. Support and shared-IP reputation are the recurring complaints, and dedicated IPs cost more.
