# Migrating from Earth Class Mail or iPostal1 to mailnow.ai

> A practical, no-mail-loss migration guide for customers leaving Earth Class Mail or iPostal1 — what's actually different, the full address-change checklist (USPS, IRS Form 8822-B, banks, state filings, vendors, subscriptions), running both addresses in parallel, filing a new Form 1583, archiving your old scans, and a realistic timeline.

Switching virtual mail providers feels riskier than it actually is — but only if you do it in the right order. The mail itself is the easy part. The hard part is the long tail of places that already know your old address: the IRS, your state's Secretary of State, your bank, your registered agent, your payroll provider, every SaaS vendor that mails 1099s, and the random subscriptions you set up three years ago and forgot about. Get the order wrong and you'll spend months chasing forwarded envelopes. Get the order right and the whole thing is quiet, boring, and done in about six weeks.

This guide is written specifically for customers leaving Earth Class Mail or iPostal1 for mailnow.ai. It walks through what's actually different, exactly what paperwork you need to file (and in what order), how to run both addresses in parallel so nothing gets lost, what to do with your existing scan archive, and how long each step really takes. We'll be honest about the things that aren't better — there are some — so you can make a clear decision instead of a hopeful one.

## An honest comparison: what's actually different

Earth Class Mail and iPostal1 are both mature, well-known providers, and they each do some things well. Before you migrate, it's worth being clear-eyed about where mailnow.ai is genuinely different and where it isn't.

What's different in mailnow.ai's favor: every envelope is opened and every page is scanned in color by default, with no per-scan or per-page fees. AI reads each item on arrival — sender, summary, dates, amounts, deadlines, check fields — so your dashboard works more like email than like a stack of envelopes. Pricing is one flat monthly fee that includes scanning, storage, and shredding. Check processing (receive, endorse, deposit, archive) is built into the same product instead of a separate integration.

What isn't necessarily better: Earth Class Mail has been around longer and has a larger network of physical addresses, which matters if you specifically need a Manhattan, San Francisco, or other premium-prestige street address. iPostal1 has the widest US footprint by a large margin — well over a thousand locations — which matters if you want a local address in a specific small city. mailnow.ai operates from a smaller set of facilities; if your primary requirement is a particular city's ZIP code on your letterhead, check coverage before you commit.

What's roughly the same: USPS Form 1583 compliance, secure scanning facilities, the ability to forward, shred, or archive items, basic search across your scans, and standard data security practices. All three providers operate as legitimate Commercial Mail Receiving Agencies (CMRAs) under USPS rules.

> **If you only need one thing to be different** — The single biggest day-to-day difference is full-page color scanning with AI summaries on every item, included in the base price. If you've been paying per-open or per-page fees and avoiding opening mail because of it, that's the change you'll feel within the first week.

## Before you start: gather what you'll need

Migrating cleanly is mostly a paperwork exercise, and paperwork is a lot less painful when you have everything in one place before you begin. Spend 20 minutes gathering the following so you don't have to stop and dig things up later.

- Your current mail address with Earth Class Mail or iPostal1, including the suite or PMB number exactly as it appears on file.
- Your business's legal name, EIN, and state of formation (you'll need these for IRS Form 8822-B and any state filings).
- A government-issued photo ID and one secondary ID (utility bill, bank statement, lease) — required for the new USPS Form 1583.
- A list of every account that mails you anything: bank, credit card, payroll, accountant, lawyer, registered agent, insurance, state tax authority, IRS, Secretary of State, and any SaaS vendor that sends 1099s, W-2s, K-1s, or paper invoices.
- Your login credentials for your old provider, so you can export historical scans and check what's been arriving recently.
- A spreadsheet or a simple checklist (we'll give you one below) to track who has been notified and who hasn't.

## The step-by-step order that avoids mail loss

Order matters. The single most common mistake is filing a USPS change of address from your old provider's address to your new mailnow.ai address before your new address is actually active — which means USPS can't deliver mail to it yet and starts returning things to sender. Follow this order and that doesn't happen.

1. Sign up for mailnow.ai and pick your new address. You'll see the exact street address and suite number you'll be using before you commit to anything.
2. Complete USPS Form 1583 with mailnow.ai. This typically takes about 15 minutes and uses online remote notarization. Until this is on file with USPS, your new address cannot legally receive mail on your behalf.
3. Wait for activation confirmation from mailnow.ai — usually within one business day of submitting Form 1583. Do not skip this step. Filing a change of address against an inactive new address is the #1 cause of returned mail.
4. Start the parallel-operation period (described below). Keep your old provider active and notify the most important senders first.
5. Update senders in priority order: government and tax (highest priority), banks and financial accounts, registered agent and state filings, payroll and benefits, customers and vendors, then everything else.
6. Once high-priority senders have confirmed the new address (typically 2–4 weeks), file a USPS change of address from your old provider's address to your new mailnow.ai address. This catches anything you missed.
7. Run in parallel for at least 30 more days after the USPS change of address takes effect, so anything still in transit lands somewhere you can see it.
8. Export and archive your old scans (covered below), then cancel your old provider.

## The address-change checklist (downloadable as content)

Use this as a literal checklist. Print it, paste it into a doc, or copy it into your task tracker. Each row is a notification you need to make at least once. The order roughly matches the priority you should work in.

| Who | What you file or update | Where | Notes |
| --- | --- | --- | --- |
| USPS — change of address | Online change of address from your old provider's address to your new mailnow.ai address | moversguide.usps.com | Do this AFTER your new address is active and AFTER you've notified high-priority senders directly. |
| IRS — business address | Form 8822-B (Change of Address or Responsible Party — Business) | irs.gov, mail to the address listed on the form for your state | Required within 60 days of any change. Update before any major filing (940/941/1120/1065/1040). |
| IRS — personal (if you used the address on personal returns) | Form 8822 (Change of Address) | irs.gov | Only if your old virtual address was also on personal tax filings. |
| State tax authority | State change-of-address form (varies by state) | Your state's Department of Revenue website | Often combined with sales tax, withholding, and franchise tax accounts. Check each separately. |
| Secretary of State — principal office address | Statement of information / annual report amendment | Your state's Secretary of State portal | Many states require an updated principal office address within 30–90 days of change. Don't confuse with registered agent address. |
| Registered agent | Notify your registered agent of the new principal office address | Your registered agent's portal | Your registered agent address typically does NOT change — only the business address. |
| Bank — business checking, savings, credit cards | Address change request (often requires in-person or notarized form) | Each bank's website or branch | Banks are the strictest. Some require a Form 1583 or proof of CMRA registration. |
| Payment processors (Stripe, Square, PayPal) | Account address update | Each processor's dashboard | Affects 1099-K reporting address. |
| Payroll provider (Gusto, ADP, Rippling, etc.) | Company address update | Payroll provider's settings | Affects W-2s and quarterly tax filings. |
| Accountant / bookkeeper / CPA | Email or portal notification | Direct to your accountant | They send a lot of paper mail; tell them early. |
| Insurance — business liability, E&O, workers' comp | Address change request to each carrier or broker | Insurance broker or carrier portal | Some policies require endorsement; do not assume an email is enough. |
| Customers and clients | Updated invoice templates, contracts, and remittance instructions | Your billing system | Update outgoing invoice address before the next billing cycle. |
| Vendors and contractors (W-9 on file) | Send updated W-9 to each vendor | Email | Ensures your 1099-NEC arrives at the new address. |
| Subscriptions and SaaS | Account billing address | Each vendor's billing settings | Catch the long tail by reviewing the last 12 months of card statements. |
| Domain registrar / WHOIS | Update business contact address | Registrar account | Especially if you receive any registrar notices by mail. |
| Trademarks / IP filings | Notify USPTO of correspondence address change | USPTO TEAS portal | If you have any active marks, this is required. |
| Professional licenses (bar, CPA, contractor, real estate) | License board address update | Each licensing board | Often has its own deadline (30 days is common). |
| Health benefits / FSA / HSA administrators | Account address update | Each administrator's portal | Affects tax forms (1095-C, 5498-SA). |
| Retirement plan administrator (401(k), Solo 401(k), SEP) | Account address update | Plan administrator portal | Affects annual 5500 filings and participant disclosures. |
| Marketing materials (website, business cards, letterhead, email signatures) | Update wherever your address appears publicly | Your CMS / design files | Do this last — after you've fully cut over. |

> **Form 8822-B has a 60-day deadline** — The IRS requires businesses to file Form 8822-B within 60 days of any change of business mailing address or responsible party. Missing it can mean important IRS correspondence goes to your old provider — and if that provider has already shredded it, you have no record it ever arrived.

## The parallel-operation period (don't skip this)

The single best thing you can do to avoid losing mail during a migration is to keep both addresses active for 60–90 days. It costs you one or two extra months of subscription fees on the old provider, and it eliminates almost all of the risk of something important falling through a crack.

During the parallel period, log in to your old provider's dashboard at least once a week. Look at what's still arriving there. Each new sender that shows up is a sender you didn't catch on your initial notification pass — note them down, update them, and keep going. After two or three weeks, the volume at your old address should drop noticeably. After six to eight weeks, it should be down to near zero. That's when you know you've actually moved, as opposed to thinking you have.

Two practical tips for the parallel period: first, when you log into your old provider, treat anything arriving there as a to-do item to update the sender — not just as mail to forward. Forwarding is a band-aid; updating the sender is the cure. Second, keep the USPS change of address as a backstop, not a replacement for direct notification. USPS forwarding is reliable but not perfect, expires after 12 months, and won't forward many classes of business mail at all (including most non-first-class items).

## Filing a new USPS Form 1583 with mailnow.ai

USPS Form 1583 is the authorization that lets a CMRA receive mail on your behalf. The form you signed with Earth Class Mail or iPostal1 doesn't transfer — every CMRA needs its own Form 1583 on file, signed by you, witnessed by a notary, and accompanied by two forms of ID. This is required by USPS Domestic Mail Manual 508.1.8 and isn't something any provider can waive.

The good news: with mailnow.ai, the whole thing is online and typically takes about 15 minutes. You'll fill out the form in your dashboard, the system pre-fills the CMRA portion (so you can't get the agent fields wrong), and you'll be connected to a live remote online notary who verifies your identity and witnesses your signature on a video call. You'll need a government-issued photo ID and one secondary ID (utility bill, bank statement, or lease). The completed, notarized form is filed with USPS automatically and your address activates within one business day.

Common mistakes to avoid: don't use a nickname or DBA on the applicant name field — use the legal name on your photo ID. Don't list the business name in the individual section if you're a single-member LLC; you'll fill out both sections. Don't use a P.O. Box as your home address (Box 7); USPS rejects these. And make sure the secondary ID is in your name and shows the same home address you're listing on the form.

## Archiving your old scans before you cancel

When you cancel Earth Class Mail or iPostal1, you typically lose access to your scan archive within 30–90 days. If you've been a customer for a few years, that archive may be the only record of important business correspondence — IRS notices, contracts, signed documents, banking notices — that you didn't think to save elsewhere. Don't let it disappear.

1. Log into your old provider and use the bulk export feature if available. Earth Class Mail allows ZIP exports of your archive; iPostal1 lets you bulk-download scans by date range.
2. If bulk export isn't offered or has size limits, sort by date and download in monthly batches. Tedious, but reliable.
3. Save the exported PDFs to a folder on your local machine, then upload the whole folder to durable cloud storage (Google Drive, Dropbox, OneDrive, or your accountant's portal). Encrypted backup is ideal for tax records.
4. Keep at least 7 years of tax-relevant scans (the IRS records-retention horizon for most situations), and keep contracts, leases, and corporate records indefinitely.
5. Confirm the export is complete by spot-checking a handful of recent and old items before you cancel the account.

> **Heads up on physical mail still in storage** — If you've asked your old provider to hold physical items, request shredding or forwarding before you cancel. Once the account is closed, retrieving held mail becomes much harder and sometimes impossible.

## A realistic timeline: what to expect, week by week

Most migrations take six to ten weeks from sign-up to fully cut over. Here's what each phase actually looks like.

| Week | What's happening | What you're doing |
| --- | --- | --- |
| Week 0 (day 1) | Sign up for mailnow.ai, pick your address, complete Form 1583 with online notary. | About 30 minutes of focused work. |
| Week 0 (day 2) | Address activates with USPS. | Confirm activation in your dashboard before going further. |
| Week 1 | Notify high-priority senders directly: IRS (Form 8822-B), state tax, Secretary of State, all banks, payroll, registered agent. | A few hours total, mostly waiting on web forms and downloads. |
| Weeks 2–3 | Notify second-priority: customers, vendors (W-9 updates), insurance, accountant, lawyer, professional licenses, retirement plan. | Email-based for most. Update outgoing invoice templates. |
| Week 4 | File USPS change of address from old to new address as a backstop. Update website, business cards, email signatures. | 5 minutes for the USPS form, longer for marketing materials. |
| Weeks 4–8 | Parallel-operation period. Monitor old provider for stragglers and update each sender as they appear. | 15 minutes per week of cleanup. |
| Week 6+ | Volume at old address drops to near zero. Most senders have caught up. | Spot-check, no major actions. |
| Week 8–10 | Export your scan archive from old provider. Verify the export. Cancel old subscription. | 1–2 hours for the export and verification. |

A few timing notes: Form 8822-B doesn't have an instant effect — the IRS typically takes 4–6 weeks to update its records, so file it early. State filings vary widely; some states process address changes the same day, others take 30–60 days. Banks are slow and often require notarization or a branch visit; start that on day one. And don't be surprised if a few stragglers (a single subscription, an obscure state form, a vendor you forgot) keep arriving at your old address for months — that's normal and what the USPS change of address is there to catch.

## Common pitfalls (and how to avoid them)

- Filing the USPS change of address before your new address is active. Mail gets returned to sender and you have no idea it happened.
- Forgetting Form 8822-B. The IRS keeps using your old address for months and important notices vanish.
- Confusing your registered agent address with your business mailing address. They're separate; usually only the latter changes.
- Canceling your old provider too early. You lose access to your scan archive and to any in-flight mail.
- Treating USPS forwarding as a substitute for notifying senders. Forwarding expires after 12 months and doesn't cover everything.
- Not updating outgoing invoice templates. Your customers will keep mailing checks to your old address indefinitely.
- Skipping the parallel-operation period to save one month of subscription fees. The risk-to-reward is wildly in favor of running both accounts for a couple of months.

## Ready to migrate?

If you've been paying per-scan and per-page fees for years, the change you'll notice first isn't the new address — it's that you actually start opening your dashboard. Mail you used to leave unopened because it cost $1.50 to find out it was junk is now read, summarized, and sorted before you ever see it. Checks land already classified and ready to deposit. The IRS notice that used to be a frosted window into a vague worry is now the first line of the summary at the top of the page.

Sign up for mailnow.ai, complete a quick Form 1583, and follow the timeline above. Six to ten weeks from now, your migration will be quietly complete — and the only thing you'll have to remember is to actually cancel the old account, because by then you'll have stopped logging into it.
