Pop3Fetch
Microsoft Outlook
Mailbird
Pop3Fetch is the email-import service Google should have left in Gmail. When Google discontinued the built-in "Check mail from other accounts" feature in 2024, millions of users lost the ability to consolidate Yahoo, Outlook, IONOS, GoDaddy, and other external mailboxes into a single Gmail inbox without setting up forwarding rules that break threading or trigger spam filters.
Pop3Fetch fixes that. It connects to your external accounts over encrypted POP3 or IMAP, fetches new mail on a schedule (down to every 5 minutes on Pro), and delivers each message directly into Gmail through the official Gmail API. Messages arrive with their original headers intact, in the right conversation threads, with no relay servers in between.
The service is zero-storage: messages stream through memory in a single transfer and are dropped the moment Gmail acknowledges delivery. Google CASA Tier 2 verified. AES-256-GCM encryption for stored credentials.

Pop3Fetch's answer:
Pop3Fetch is the only service that pairs the official Gmail API delivery path with a real productized SaaS. Every alternative in the category is one of three things: a free hobby project (usually POP3-only, no support, no security story), an older commercial forwarding service (SMTP relay, breaks threading, triggers spam filters), or the original Google feature โ which no longer exists. Pop3Fetch uses Google's official Gmail API to import mail exactly the way Gmail's own retired fetcher used to, adds IMAP support the old feature never had, and does it with verified security (Google CASA Tier 2, AES-256-GCM credential encryption, zero-storage pass-through).
Pop3Fetch's answer:
Three reasons. First, delivery method: Pop3Fetch imports through the Gmail API, so original senders and headers arrive intact โ no spam-flag risk, no broken conversation threading. Every competitor that uses SMTP forwarding fails on at least one of these. Second, protocol support: both IMAP and POP3 (most alternatives are POP3-only, which excludes Yahoo Mail, iCloud, and any modern provider that deprecated POP3). Third, security posture: Google CASA Tier 2 verified, OAuth 2.0 with write-only scopes by default, AES-256-GCM credential encryption, and a zero-storage architecture where message bodies never touch our database. Bonus: a real freemium pricing model that starts free forever for one account, no credit card required.
Pop3Fetch's answer:
People who used to rely on Gmail's "Check mail from other accounts" feature and lost that workflow when Google retired it. That's mostly small business owners and freelancers consolidating Yahoo, Outlook, IONOS, GoDaddy, and custom-domain mailboxes into Gmail; solo founders and consultants who prefer one Gmail inbox to tab-hopping between webmail interfaces; and anyone who tried Google's recommended SMTP-forwarding workaround and watched it break threading or land legitimate mail in spam. Secondary audience: privacy-conscious users who specifically want the zero-storage pass-through architecture instead of a forwarding service that persists their mail.
Pop3Fetch's answer:
Google discontinued Gmail's built-in "Check mail from other accounts" (POP3 fetcher) feature after more than a decade of service. Millions of Gmail users โ small businesses, freelancers, families with legacy Yahoo or Outlook accounts โ lost the workflow that let them consolidate external mailboxes into a single Gmail inbox. Google's suggested replacement (SMTP forwarding rules) breaks conversation threading, gets flagged as spam, and strips authentication headers like SPF and DKIM, meaning legitimate mail routinely lands in the wrong folder or doesn't arrive at all. Pop3Fetch was built specifically to fill that gap, using the official Gmail API to import mail exactly the way Gmail's own retired fetcher did โ with all the reliability, security posture, and reach the original feature had, plus IMAP support it never offered.
Pop3Fetch's answer:
Backend: Python and Flask for the web app; a separate Python worker for the background IMAP/POP3 polling. Delivery: Google Gmail API via OAuth 2.0 with write-only scopes by default. External mailbox access: standard IMAP and POP3 over TLS. Credentials: AES-256-GCM encryption. Data store: PostgreSQL. Hosting: Render (application + worker) and Netlify (marketing site). Security posture is validated under Google's CASA Tier 2 program.

I am thankful for a platform like CodeSandbox because it allows me to offload majority of the processing power and memory resources to the cloud. With a local VS Code installed, I can tunnel in via a remote connection to work on my projects, tinker, or do a deep-dive on certain topics; all while ensuring that the RPi 4 still has sufficient resources left to run other things in the background. - Source: dev.to / over 1 year ago
