Loops
Email for SaaS: marketing + txn
Free tier + paidEmail, forms & notificationsloops.so
What it is
Email platform aimed at SaaS products, combining transactional sends, lifecycle sequences and marketing campaigns in one dashboard. Billing is per stored contact, not per send — paid plans include unlimited sending at up to 1,000 emails per second. Includes a visual editor, events API and segmentation.
Why it earns a slot
One tool for the welcome email, the onboarding drip and the password reset, so you are not stitching Resend plus Mailchimp together. The UI is clean enough that a non-technical cofounder can edit copy.
Know before you commit
Per-contact billing means a big dormant list costs money even if you never email it. The jump from free straight to $49/mo is steep for a pre-revenue project.
Neighbourhood
How Loops sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
