mySMTP Sending Policy
mySMTP provides a secure and reliable platform for sending legitimate email. This Sending Policy protects our customers’ sender reputation, maintains high delivery standards, and prevents spam, fraud and other unacceptable use.
This policy applies to all email sent through mySMTP and forms part of our Terms and Conditions.
Spam and abuse prevention
mySMTP uses automated security controls and manual monitoring to identify suspicious activity, compromised accounts, false identities, payment fraud and other forms of abuse.
Payments may be protected by 3D Secure and the payment providers’ own fraud-prevention systems. We may reject an order, restrict an account or request additional documentation if we identify a risk of fraud or abuse.
Recipient lists and legal basis
Customers must have a valid legal basis for contacting each recipient.
Where consent is required, the Customer must be able to demonstrate that the recipient has provided valid consent. Other messages, including order confirmations, invoices, security notifications and password resets, may rely on a different legal basis.
Purchased, rented, shared, automatically generated or scraped recipient lists are not permitted unless the Customer can demonstrate a valid legal basis for contacting each recipient.
Recipient lists must be accurate, properly maintained and free from known invalid addresses, unsubscribed recipients and previous spam complainants.
Bounce rates
The total bounce rate should not normally exceed 5% for any mailing.
A high bounce rate may indicate outdated or invalid addresses, insufficient list maintenance or the use of recipient data from an unknown source.
mySMTP may restrict or stop a mailing if the bounce rate exceeds our limit or if the mailing may damage the sender reputation of the Customer or mySMTP.
Customers should validate and clean their recipient lists before sending. This reduces unnecessary usage and protects the reputation of their domains and IP addresses.
Spam complaints and sender reputation
mySMTP monitors relevant delivery signals relating to sending IP addresses and domains. These may include:
- Bounce rates
- Spam complaints
- Blocks and rejections
- Invalid or inactive recipients
- Unusual changes in sending volume
- Signs of compromised accounts or other suspicious activity
If a mailing exceeds our internal thresholds or creates a risk to delivery performance, we may temporarily restrict the account or stop the mailing.
Where possible and appropriate, we will contact the Customer to investigate the cause and agree on the necessary corrective action.
Prohibited use and content
mySMTP must not be used for spam, phishing, fraud, deception or other unlawful activities.
The following content and activities are not permitted without mySMTP’s prior written approval:
- Pornographic or sexually explicit material
- Tobacco, e-cigarettes and related products
- Illegal drugs, controlled substances and unlawful pharmaceuticals
- Weapons, ammunition and military equipment
- Political campaign material and ideological propaganda
- Hacking tools, exploits, malware and illegal software
- High-risk cryptocurrency, investment or financial promotions
- Multi-level marketing, pyramid schemes and “get-rich-quick” offers
- Content that promotes violence, self-harm or illegal activity
This list is not exhaustive. mySMTP may reject content, industries or mailings that, in our reasonable assessment, present an unacceptable legal, security or reputational risk.
If you are unsure whether your content or business model is permitted, contact
