Frequently Asked Questions

Yes — for most businesses, because 100,000 emails per month is a very large allotment. GoodSender is pay-as-you-go: the first 100K emails per month cost $0, and that allotment covers every outbound email — transactional templates, consent-request emails, and marketing sends to consented recipients — all drawing from the same single 100K bucket. 100K a month is roughly 3,300 emails a day, which is more than most SaaS apps, side projects, and small-to-mid-sized businesses ever send, so in practice the monthly bill stays at $0 for the majority of users. Only a small fraction sustainably cross the threshold; if you do, it's $1 per additional 100K — no subscriptions, no tiers, no credit card required to start.

Every outbound email. Transactional template sends (MFA Enrollment, New Device, Login, Order Completed, OTP Code), marketing sends to consented recipients, and the consent-request emails the Permission Loop sends all draw from the same 100,000-per-month allotment. One bucket, one counter — no per-type splits, no tiered accounting, nothing to reconcile at the end of the month. Consent is a gate on what you're allowed to send to a recipient, not a discount on what gets counted.

SendGrid removed its free plan in May 2025 and starts at $34.95/month for 100K emails. Resend starts at $35, Mailgun at $75 for the same volume. GoodSender is $0 for 100K and $1 per 100K after that — with consent management and transactional templates built in.

Call the consent endpoint with a list of recipient emails. GoodSender sends each recipient a short, high-reputation consent email with two buttons: approve and reject. When they click approve, their consent is granted and you can send to them instantly across your workspace.

Yes — it's the pattern we recommend. The standard flow: (1) collect the recipient's email on your own signup form or account creation. (2) Call GoodSender's consent endpoint with that address. We send the consent confirmation email. (3) The recipient clicks approve (or reject). (4) Only after approve can you send marketing or custom transactional mail (not templates) to them. Until approve is clicked, every send attempt to that address is discarded inside GoodSender — the approval click is a hard gate, enforced, not a convention. The consent endpoint is a tool for implementing double opt-in, not a license to cold-email — using it to contact people who never expressed intent will tank your sender reputation regardless of what the API technically allows.

A reject click suppresses the address — no emails go out. The original consent email stays live, so if the recipient changes their mind and clicks approve in that same email, the suppression is lifted and consent is granted. If they never click at all, the address simply stays unconfirmed and every send attempt is discarded. Only an approve click ever opens the gate.

Yes. Bulk-submit the addresses to the consent endpoint and GoodSender will gradually collect consent on your behalf. Recipients who confirm are unlocked; the rest are safely skipped.

Yes — for any mailbox provider that offers a feedback loop (FBL). GoodSender runs on Laneful, which is registered with the major FBL programs (Yahoo, Microsoft/Outlook, AOL, Comcast, and others). When a recipient on one of those providers hits "Mark as spam," Laneful receives the complaint in ARF format and automatically adds that address to a workspace-level suppression list — you physically cannot send to them again from any API key in that workspace. Suppression is scoped to the workspace, not the whole platform: if a different GoodSender customer has independently collected consent from the same recipient, their sending is unaffected. Gmail is a gap worth knowing about — Gmail doesn't run a traditional FBL, so complaint data is only exposed in aggregate via Google Postmaster Tools. Individual Gmail users who mark you as spam are not auto-suppressed; what protects you there is aggregate reputation.

GoodSender sends from a shared IP pool dedicated to GoodSender traffic — separate from Laneful's general commercial pools. Because every recipient on this pool has either confirmed consent through the Permission Loop or received a permitted transactional template, the pool carries a very high reputation by design: mailbox providers see an unusually low complaint rate and high engagement. No warm-up required — the pool is already warm, so new customers send at full volume from day one. Past 100,000 emails per month, senders are automatically moved onto dedicated IP allocation and other reputation infrastructure, managed by GoodSender; you don't need to request it, pick a tier, or handle warm-up yourself.

Not inside GoodSender, today. We deliberately keep the GoodSender surface focused on the consent workflow — the deliverability heavy-lifting (FBL handling, automatic suppression, the curated shared pool) happens under the hood on Laneful. In the common case, if you're sending to consented recipients only, those numbers stay healthy on their own. If you do need that visibility — complaint rates and bounce analytics in a dashboard, Google Postmaster Tools integration, IP reputation reporting, an API to pipe deliverability metrics into Datadog or Grafana — that's what Laneful is for. GoodSender and Laneful are built by the same team on the same infrastructure, so when your volume or compliance needs outgrow the free tier, Laneful is the direct upgrade path with full operational visibility out of the box.

Yes. Transactional emails use predefined templates and do not require any recipient consent. Pick a template (MFA Enrollment, New Device, Login, Order Completed, OTP Code), pass personalization data, and send immediately.

MFA Enrollment, New Device, Login, Order Completed, and OTP Code. Each template ships with an HTML body, a plain-text body, and a typed variable schema. This is the launch set — the catalog grows over time, expanding little by little based on what customers ask for. If you need a template we don't offer yet, let us know and we'll consider adding it.

Not yet. Today the templates in the launch catalog (MFA Enrollment, New Device, Login, Order Completed, OTP Code) ship with a fixed HTML body, plain-text body, and a typed variable schema — you pass `variables` (company name, user name, code, etc.) and we render and deliver inbox-tested HTML across 90+ clients. Custom template HTML is on the roadmap. If it's a blocker for you, let us know — customer demand is what decides what we ship next.

GoodSender is built by Joy Labs Ventures, founded by Isaac Saldana (co-founder of SendGrid) and former SendGrid team members. It runs on Laneful, enterprise email infrastructure operated by the same team.

DKIM, SPF, and DMARC are configured automatically when you verify your domain. Adding your domain takes ~5 minutes and unlocks sending from any address on that domain.

GoodSender runs on Laneful, enterprise email infrastructure operated by the same team that built SendGrid. Laneful is SOC 2 compliant and GDPR-aligned: recipient data, consent state, and sending metadata are handled under those controls. Email bodies are not retained after delivery beyond the minimum required for bounce handling and deliverability analytics.

The free tier ships at best-effort. Paid usage inherits Laneful's commercial SLA (99.9% uptime on the send API). Contact us for custom enterprise terms.
