Transactional
SendLayer
Transactional email delivery with simple annual plans.
overview
SendLayer is a transactional sender focused on API and SMTP relay, domain authentication, logs, suppression management, bounce handling, blocklist monitoring, event webhooks, and analytics. Plans are simple but billed annually, and the entry plan is small at 1,000 emails per month.
deliverability
Transactional sender with authentication, active anti-spam, bounce handling, blocklist monitoring, and event-based webhooks. Public independent deliverability history is thinner than Postmark or SMTP2GO.

not great for
Teams that want monthly billing or large free-tier volume.
