Loops vs SendGrid
Loops and SendGrid both answer the same question: how do your emails actually get delivered? Email built for software companies, blending transactional sends with lifecycle campaigns triggered by product events. The incumbent high-volume sender, now part of Twilio, covering both transactional and marketing mail at scale. SendGrid covers more of the ecosystem, so it survives a change of framework; Loops is the better fit while you stay where it is strongest.
