Deliverability
Sending limits and warm-up for new accounts, bounces, spam complaints, suppressions and one-click unsubscribe in Maillayer.
Deliverability is whether your email lands in the inbox instead of spam. Maillayer handles the technical parts for you; this page explains what happens and how to keep your reputation strong.
Daily sending limits#
New accounts warm up over their first 14 days after the first purchase. It protects your domain and our shared IPs:
| Days | Emails a day |
|---|---|
| 1 to 3 | 1,000 |
| 4 to 7 | 5,000 |
| 8 to 14 | 20,000 |
| 15 onward | 50,000 |
Limits reset at midnight UTC. Need more sooner? Contact us. For a big list from a new domain, also use campaign warmup.
Bounces, complaints and suppressions#
- Hard bounces (the address doesn't exist) and spam complaints add the address to your suppression list. It never gets email from you again, campaign or transactional.
- Unsubscribes block campaigns only, so people still get receipts and password resets.
- Suppressed addresses are dropped before sending and don't use credits.
Unsubscribe#
Every campaign has an unsubscribe link in the footer and the one-click unsubscribe headers Gmail and Yahoo require, so readers can leave from the inbox itself.
Authentication#
Your email is signed with DKIM and aligned with SPF and DMARC on your own domain. See Verify a sending domain.
Good habits#
- Only email people who agreed to hear from you. Never buy lists.
- Keep contact checks on, and remove people who haven't opened in months.
- Keep your bounce rate under 2% and spam complaints under 0.1%.
- Send from a consistent address and at a steady pace.
