Integration details
Description
SecureSMTP is an email sending service for websites and apps: password resets, receipts, order updates, contact form notifications and other emails your software sends. Connect your SecureSMTP account to: - check your plan and how many emails you can still send this period - see your sending domains, whether each one is verified, and the DNS records it needs - add a new sending domain and get the exact DNS records to publish - check a domain's DNS records and mark it verified once they are correct - see how your email performed over the last 30 days: delivered, bounced, marked as spam and failed - send a one-off email from your account after you confirm the recipients, subject and text When you connect, you sign in to SecureSMTP and choose one of your sites. The connector only sees and acts on that site. Emails sent through it follow the same rules as the rest of your account: your sending allowance, spam checks and the suppression list (addresses that bounced or asked not to receive mail) all apply. It does not send bulk or marketing email. You need a SecureSMTP account. You can create one at securessmtp.com.
