Many businesses in Antigua and Barbuda send important email from software, not from a person: a hotel booking engine confirming a reservation, an online shop sending an order receipt, a bank portal issuing a password reset, a property manager’s system sending invoices. If those messages come from a shared web server or a basic mailbox, they often land in spam or never arrive. An SMTP relay fixes that.
What Mailpro’s SMTP server does
You point your application or website at Mailpro’s SMTP service instead of your hosting provider’s mail server. Mailpro then handles delivery: queuing, retries, bounce handling and reputation management. Your messages go out from infrastructure built for sending, with deliverability routing and IP reputation management. In Mailpro’s own customer survey, email deliverability was rated 9.6/10.
Common uses on the islands
- Hotels and villas: reservation confirmations and pre-arrival details from the property management system.
- E-commerce and retail: order confirmations and shipping updates for local delivery across Antigua and to Barbuda.
- Financial services: statement notifications, one-time codes and account alerts.
- Websites: contact-form notifications from WordPress and other platforms.
- Professional firms: document-ready notices from client portals.
Security and data location
Transactional emails often contain personal data: names, booking details, amounts. Antigua and Barbuda’s Data Protection Act, 2013 requires data users to protect personal data, taking account of where it is stored and how it is transferred, and to make sure their processors give sufficient security guarantees (section 8). Mailpro runs on private infrastructure in Switzerland, outside US jurisdiction, encrypts connections with TLS 1.3, and never sells or rents data. That matters especially for banks, insurers and firms serving international clients.
Authentication
Set up SPF, DKIM and a DMARC record on your domain so mailbox providers can verify your messages. Gmail and Yahoo now require this for bulk senders, and it protects your brand from spoofing.
Setting it up
- Create a Mailpro account and open the SMTP settings to get the server name, port and credentials.
- Enter them in your application’s outgoing mail settings, using port 587 or 465 with encryption.
- Add the SPF and DKIM records Mailpro provides to your domain’s DNS. If your domain is managed by a local web host, send them the records.
- Send a test booking or order and check that it arrives and shows in the reports.
Plan the switch outside your peak season, so any teething problems do not coincide with the winter rush or regatta week.
SMTP or API?
SMTP is the quickest option when your software already has an “outgoing mail server” setting. If you are building a new integration, an API may suit better. Compare them on our page about API versus SMTP.
