Troubleshooting

Email not sending or landing in spam

Fix SMTP authentication, the right ports, and SPF/DKIM so your mail is delivered.

Can't send at all? Almost always an outgoing (SMTP) setting:

  • Turn SMTP authentication ON in your mail client — use your full email address and password.
  • Use port 465 (SSL) or 587 (STARTTLS), not port 25 (often blocked by ISPs).

Your mail lands in recipients' spam? Add these DNS records (see Add DNS records):

  • SPF — a TXT record on @ authorising our server to send for your domain.
  • DKIM — signs your mail; open a ticket and we'll provide the record for your domain.
  • DMARC — a TXT record on _dmarc that tells receivers how to treat unaligned mail.

Sending bulk newsletters from shared hosting is discouraged and hurts deliverability — use a dedicated service (Mailchimp, Brevo, Amazon SES) for campaigns and keep your domain mailbox for real correspondence.

Still need a hand?

Open a ticket from your dashboard with your domain and a screenshot — our team replies fast.
