Here’s how SafeToSend corrects complex errors and protects your file from toxic addresses.

Undeliverable and harmful addresses can lead to blocking and blacklisting by ISPs. Even something as innocent as a typo on a registration form can mean a lost opportunity to connect with a valuable customer. Use FreshAddress’s SafeToSend to neutralize these threats with a bulletproof method of separating the good addresses from those that are not safe to email.

It’s time you get comprehensive protection against the costly fallout of problematic addresses. Unlike services that merely validate or verify addresses, our SafeToSend service ensures flawless list hygiene with a robust three-step screening process:

STEP 1: CHECK

To make sure it’s deliverable, we:

  • Determine whether the address syntax conforms to RFC (82228225322369652336530) and FreshAddress standards.
  • Check each address in real time to confirm that the upper and lower domains and associated MX (mail exchanger) records are valid and can accept mail.
  • Ensure address meets ISP-specific requirements.
  • Verify the account is linked to an actual working mailbox. (Our proprietary algorithm for this process includes a vast database of recent email deliverability findings and a real-time SMTP check.)

STEP 2: CORRECT

To maximize the number of safe, deliverable addresses on your list:

  • Our patented spell-check technology corrects as many as seven errors in a single address and fixes any typos, including:
    • Misplaced or transposed @ signs and invalid characters such as spaces or quotes.
    • Typos in both TLD’s (.com, .net, .edu, etc.) and LLD’s (gmail, aol, Hotmail, etc.)
    • ANY misspelled domain, not just the most popular ones.
  • Our proprietary algorithm will also suggest alternative domains for uncommon entries (such as @gmail.com instead of @google.com).
  • Every corrected email addresses included in your file is 100% guaranteed to be valid and deliverable.

STEP 3: PROTECT

We check each email address against our vast knowledgebase to identify and flag for removal any damaging (but deliverable) email addresses, including:

  • Toxic: Spamtraps and honeypots.
  • Undesirable: Frequent complainers, role accounts, disposable domains, fictitious and malicious email addresses, client-specific suppressions.
  • Not best-practice: DMA “Do Not Email List” and FCC wireless domains

When the process is complete, we provide you with the following results for each address:

  1. Confirmation that it is valid (or bouncing/undeliverable).
  2. A comment detailing our findings (e.g., bad top level domain, syntax error, etc.)
  3. A corrected email address, if applicable.
