Deliverability handled on every send

Loops signs every email, watches each send, and stops mailing addresses that bounce or complain. You add a few DNS records and send to people who signed up.

Safeguards that run without you

Checks, suppression, and retries run on every send.

Send monitoring

Loops watches content, volume, and sending patterns as mail goes out.

Automatic suppression

A hard bounce or spam complaint stops every future send to that address.

Retries and pacing

Soft bounces are retried. Campaigns go out in rate-limited batches.

Checks before you send

Guardian flags missing fallbacks and buttons without links before an email goes out.

Authentication you copy once

Loops writes the records for you. Add them yourself, or hand a zone file or records page to whoever runs your DNS.

A setup that protects your sender reputation

Your domain carries your sending history, so pick it once and keep it.

Send from a subdomain

Use something like mail.yourcompany.com, a name people recognize in the From field.

Keep one domain

One steady sending history beats several thin ones. Lists let people pick what they get.

Register with Apple

Register your sending domains with Apple so Hide My Email addresses don’t bounce.

Show your logo

A sending avatar, and BIMI once authentication is set, puts your logo in the inbox.

Clean lists from the first signup

Stop bad addresses at signup, then send to people who still engage.

Email blocklist

Block an address, a domain, or a whole TLD across forms, uploads, and the API.

Double opt-in

Unconfirmed form sign-ups stay out of marketing sends.

Forms with abuse protection

Loops forms include rate limiting and basic abuse protection.

Engaged segments

Send campaigns to recently active contacts. Third-party list cleaning flags valid addresses.

Watch the signals yourself

Loops reports what it sees and points you to what it can’t.

Bounces in your metrics

Every email shows its bounces and spam reports, in the app and the API.

Suppression API

Check if a contact is suppressed. Paid plans can lift it once the address works again.

Google Postmaster Tools

Gmail doesn’t report complaints to Loops. Postmaster Tools shows your Gmail spam rate.

An agent that audits your setup

The Loops email best practices skill reviews sender setup, lists, and content in your project.

Frequently asked questions

Does Loops guarantee inbox placement?

No email provider can. Inbox placement depends on your domain and its history, the sending IP, your content, how often you send, and blocklists. Loops handles the parts it controls: authentication, suppression, retries, pacing, and send monitoring.

Which DNS records do I need to send with Loops?

SPF, DKIM, and MX records, plus a DMARC record. Loops shows all of them under Settings → Domain with copy buttons, a zone file download, and a shareable records page. Add them at your DNS provider, then click Verify Records.

What happens when an email bounces or gets marked as spam?

A hard bounce or a spam complaint adds the contact to your suppression list, and later sends to them show as hard bounces instead of going out. Soft bounces are retried. Gmail doesn’t pass spam complaints back to Loops, so use Google Postmaster Tools to watch Gmail.

Should I send from a subdomain?

Yes. Loops recommends a subdomain like mail.yourcompany.com or hey.yourcompany.com over your root domain. It doesn’t need to exist before you add it, because Loops gives you every record it needs.

Can I send from more than one domain?

You can, but one domain usually does better because its sending history stays in one place. To separate newsletters from product updates, use mailing lists on the same domain. If you do need a second domain, create a second team in Loops. Teams don’t share settings or contacts.

Do I need a domain warmup tool?

No. Warmup tools trade automated emails between seeded inboxes, and mailbox providers weight real recipients. Start by sending welcome emails to new signups, then add recently active users in batches.
