Direct Mail Manager vs Lob Address Verification

Direct Mail Manager automates targeted postcards and letters, from campaign setup through entry into the mail stream. Recurring campaigns can run automatically, and uploaded contact data supports one-to-one personalization with dynamic HTML templates. Real-time tracking follows each mailer from facility departure to the recipient’s mailbox. Address verification validates USPS and non-postal addresses, while list tools import records, correct errors, segment lists, match suppression lists, and create custom fields and filters. Native integrations are listed for Salesforce, Shopify, QuickBooks, CapsuleCRM, Planning Center, and Zapier. The REST API sends single pieces or batches in real time and exposes mail status. The service states that it is HIPAA compliant for patient-related mailers. Plans include a free Starter tier, a $199 a month Pro plan, and Enterprise pricing on request. Pro includes three users, unlimited address sends, unlimited verifications, and 300 API calls per minute.

Lob Address Verification checks address data to help determine whether addresses can be delivered. Its APIs validate one address or a batch, and Lob says it can also check and standardize addresses while customers enter them on a website. Results can add delivery and geographic details, including ZIP+4, carrier route, address type, latitude and longitude, plus a confidence score based on its mail delivery data. The product page lists delivery data for more than 240 global territories and USPS CASS certification. Integrations include AV Elements, Shopify Address Cleanser, Airtable Address Cleanser and Zapier; the interactive demo provides examples in cURL, TypeScript, Node, Ruby, Python, PHP, Java, Elixir and C#. Lob says it encrypts data in transit with TLS 1.2+ and at rest with AES-256, and provides automatic redaction and data retention policies. Developer has no subscription fee; listed paid pricing starts at $20/mo (annual). A 30-day Enterprise trial is available for high-volume senders; print and postage are billed separately at discounted Enterprise rates.
