Email marketing for agencies, built into a CRM you own

Yes. Email sends through your own provider account (transactional mail via Postmark, bulk campaign mail via SendGrid), so the sending reputation and the bill are yours. You can set one provider at the agency level and have it cascade to every client account, or let each client connect their own in self-service mode.

Yes. Credentials resolve per sub-account first, then brand, then agency, so a client in self-service mode sends entirely under their own domain, provider account, and reputation, separate from every other client on your install.

Yes. There is a global suppression list per account (covering unsubscribes, bounces, spam complaints, manual entries, and SMS STOP), applied to every send automatically. You also get a sending-domain checker for SPF, DKIM, DMARC, and MX records, domain warmup with daily DNS checks, throttle and stagger controls, and a per-provider breakdown of where mail is and is not landing.

Yes. Double opt-in is available on signup forms: a new subscriber gets a branded confirmation email and is only added to the list after they click it. It is off by default and set per form, so you turn it on only where you want confirmed opt-in.

The usual four are: broadcast or newsletter sends (one message to a segment at once), promotional or offer emails, lifecycle and retention emails (onboarding, re-engagement, win-back), and transactional or triggered emails (receipts, reminders, confirmations). Seedly covers all four: broadcasts and sequences handle the first three, and Transactional lists keep receipts and account notices reaching contacts even after they opt out of marketing.

Almost every email platform charges a recurring fee that climbs with your contact count, so the cheapest option keeps getting more expensive as your clients grow. Seedly takes the other side: you buy the source code once, own it, and pay no per-contact or per-seat email fee ever again. Your only ongoing email cost is your sending provider's pass-through rate, which is a fraction of a managed platform's per-contact pricing. Across an agency running many client lists, buy-once ownership is the cheapest path by a wide margin.

You can bring your contacts in by CSV import with field mapping. To keep existing opt-outs honored, add your already-unsubscribed addresses to the suppression list, which also accepts CSV import, so those contacts stay suppressed on every send. Email templates are rebuilt in Seedly's block editor.

Yes. You own the code, so the block editor, the warmup curve, the analytics, and the send pipeline are all yours to change or extend, rather than being locked to a vendor's roadmap.
