Loops
Pros
- + Unlimited marketing and transactional sends on every paid plan, priced by contacts
- + Marketing and transactional email share one platform and one contact model
- + Free plan stores unlimited contacts and includes all platform features
- + No per-seat charges and no credit card required to start
- + Refreshingly candid pricing documentation, including machine-readable pricing
- + Developer-first API with SDKs for transactional and marketing sends
Cons
- - Steep jump from the free plan (1,000 contacts) to the first paid tier ($49/month)
- - Dormant subscribed contacts cost money every month — list hygiene is mandatory
- - Thinner automation and segmentation depth than mature marketing platforms
- - Small vendor (YC W22, roughly a dozen people) with a short track record
- - No published SLA outside Enterprise; infrastructure and deliverability details are scarce
Postmark
Pros
- + Transactional/broadcast stream separation protects application email reputation
- + Real free tier: 100 emails/month forever, no expiry — good for evaluating deliverability honestly
- + Published, tiered pricing with explicit overage rates and no sales-gated numbers
- + Deep per-message delivery and bounce analytics with sandbox testing mode
- + Boring in the good way: stable SMTP/API since 2010 with the team carried through the 2022 acquisition
Cons
- - Per-email cost is well above SendGrid at volume
- - No marketing campaigns, contact lists, or automation — transactional and broadcast sending only
- - Inbound processing, long retention, and dedicated IPs gated behind higher tiers and volume minimums
- - Owned by ActiveCampaign since 2022; long-term product consolidation is a real, if mild, risk
