This comprehensive guide will walk you through the essential concepts and practical steps needed to master this topic. By the end of this article, you'll have a solid understanding of the key principles and be ready to implement them in your workflow.
How to Connect an Email Account in Oppora.ai
What You’ll Learn
Learn how to connect Gmail, Outlook, or a custom mailbox, what each column on the Email Accounts page means and what to do when a mailbox shows Disconnected.
Every campaign and warmup run needs at least one connected mailbox. Connecting takes about a minute, and you can attach as many mailboxes as your plan allows — more mailboxes means more safe daily volume.
Steps to connect a mailbox
Step 1 — Open Email Accounts
- From the left panel, click Email Accounts.
Step 2 — Click Connect Email
- Choose your provider and sign in: Gmail, Outlook (Microsoft), or any custom provider (for example, GoDaddy). Oppora never stores your password — the connection uses your provider’s own sign-in.
Step 3 — Review the new row
- Your mailbox appears in the list with its connection status, sending limit, and warmup status.
Email Accounts — every connected mailbox with its connection status, daily limit, sends, and warmup status.
What each column means
Reconnecting a disconnected mailbox
- Click Reconnect on the mailbox row and sign in again. The Do Today list on your Home dashboard also links straight to any mailbox that needs reconnecting.
- While a mailbox is disconnected, its campaign sends and follow-ups wait — follow-ups always come from the original mailbox to keep the conversation in one thread, and they resume when it’s available again.
💡 Tip: Connect mailboxes on domains you own rather than free Gmail/Outlook addresses where possible — you’ll need DNS control for a custom tracking domain and email authentication, and your own domain builds reputation you keep.
FAQs
Q1: How many email accounts can I connect?
It depends on your plan — plans include a maximum number of connected mailboxes (for example, 50). See oppora.ai/pricing for current limits.
Q2: Can two campaigns share the same mailbox?
Yes. The mailbox takes turns across campaigns, and its personal rest gaps and daily limit are respected no matter how many campaigns use it — the campaigns effectively share its total capacity.
Q3: Why did my mailbox show Disconnected?
Only real login problems trigger it — most commonly a changed password or revoked access. Reconnect from the Email Accounts page. Temporary provider slowness is retried automatically and never shows as Disconnected.
Q4: Does connecting a mailbox start sending anything?
No. Nothing sends until you start a warmup run or launch a campaign that uses the mailbox.
Conclusion
Connecting mailboxes is the first step of every outbound setup. Once connected, head straight to warmup — the next article — before any campaign uses the mailbox.

How to Warm Up an Email Account in Oppora.ai
What You’ll Learn
Learn why warmup is non-negotiable for cold email, how to start a run, what the Progressive, Steady, and Custom strategies mean, and how to read your warmup history.
A brand-new mailbox that suddenly sends 50 cold emails a day looks like a spammer to inbox providers. Warmup fixes that: Oppora sends gradually on the mailbox’s behalf so its sender reputation grows before real campaigns rely on it. Skipping warmup is the #1 cause of spam-folder placement.
⚠️ Warm a new mailbox for at least 14 days — and up to 45 days for a completely new domain — before heavy sending. Keep warmup running even after campaigns start.
Steps to start a warm-up run
Step 1 — Open the mailbox
- Go to Email Accounts and click the mailbox you want to warm. Its header shows today’s warmup sends (for example, 3 / 20 today), the current status (Warming), and Pause / Stop controls.
Step 2 — Choose a strategy on the Configuration tab
Step 3 — Set volume and schedule
- Daily emails and Max emails control the run’s volume; Send on picks the days, and the hour range (for example, 9 AM – 5 PM) sets the sending window.
The Configuration tab — strategy, daily volume, send days, and hours. Settings lock while a run is active.
⚠️ Settings lock while warming. To change them, stop the run and start a new one — this protects your ramp from being disrupted mid-warmup.
Step 4 — Monitor, pause, or stop
- Pause temporarily halts sending and can be resumed; Stop ends the run for good (it will appear as Cancelled in history).
Reading your warm-up history
The History tab logs every completed and stopped run with its strategy, timeline, inbox rate, and emails sent — useful when you’re deciding whether a mailbox is ready for campaigns.
Warmup history — a log of completed and cancelled runs with strategy, timeline, inbox rate, and sends.
FAQs
Q1: How long should I warm up before launching campaigns?
Minimum 14 days for a new mailbox; up to 45 days for a completely new domain. If in doubt, let a Progressive run finish before heavy sending.
Q2: Can I change warmup settings mid-run?
No — settings lock while a run is active to protect the ramp. Stop the run and start a new one with the settings you want.
Q3: Should I stop warmup once campaigns are live?
No. Keep warmup running alongside campaigns — it maintains the reputation your campaigns depend on.
Q4: What’s the difference between Pause and Stop?
Pause halts sending temporarily and can be resumed; Stop ends the run permanently and records it as Cancelled in history.
Q5: My mailbox paused itself during a campaign — why?
Too many bounces or rejections in a day (the per-mailbox threshold defaults to 20 per day, or a 15% failure rate once 100+ have been sent that day). It protected its own reputation. Check list quality, run warmup, then restart the mailbox manually.
Conclusion
Warmup is the slowest part of outbound setup and the easiest to get right: start a Progressive run on day one, don’t touch it, and let the health score tell you when the mailbox is ready.

Understanding Your Mailbox Health Score in Oppora.ai
What You’ll Learn
Learn what the 0–100 health score measures, what SPF, DKIM, DMARC, and blacklist checks mean, and how to respond when your score drops or emails start landing in spam.
Each mailbox’s Overview tab answers one question: how ready is this mailbox to send cold campaigns? The health score condenses authentication, blacklist status, and real sending results into a single 0–100 number with a label (for example, 65 · Fair).
The Overview tab — health score, SPF/DKIM/DMARC checks, blacklist status, sending stats, daily activity, and deliverability.
What the Overview shows
If your score drops or spam rate climbs
- Pause campaigns that use this mailbox — keep warmup running, not campaign sends.
- Confirm SPF, DKIM, and DMARC are all green; fix any missing record at your DNS host first.
- Check the blacklist card; if flagged, reduce volume and let warmup rebuild reputation.
- Review recent list quality — bounces from unverified addresses are the fastest way to sink a score.
- Follow the golden rules in the next article before resuming volume (2–3 mailboxes per domain, 30–50/day per mailbox).
💡 Tip: Treat the health score like a credit score: it climbs slowly and falls fast. Checking it takes ten seconds — make it part of the same morning routine as Ora’s Pulse.
FAQs
Q1: What’s a good health score?
Higher is better, and the label tells you how to read it — a mailbox marked Fair or High Risk should stay on warmup and light volume until it improves.
Q2: What are SPF, DKIM, and DMARC in one line each?
SPF lists which servers may send for your domain; DKIM cryptographically signs each email; DMARC tells receivers what to do when the first two fail. Together they prove authenticity.
Q3: What does the blacklist check cover?
Public reputation lists such as SURBL and Spamhaus DBL. Being listed hurts deliverability everywhere — if it happens, cut volume and rebuild with warmup.
Q4: My inbox rate is low but my score looks okay — which do I trust?
Act on the worst signal. A low inbox rate on the current run means recipients aren’t seeing your mail regardless of the composite score — slow down and investigate.
Conclusion
The health score turns invisible reputation into a number you can act on. Green authentication, clean blacklists, and a steady inbox rate mean the mailbox is earning its place in your campaigns.

Email Deliverability Best Practices: The Golden Rules
What You’ll Learn
The five rules that keep cold email out of spam, the honest math on sending speed, and what every deliverability warning means.
Deliverability isn’t a switch — it’s the sum of how your domains, mailboxes, lists, and links behave. These five rules are how high-volume senders stay in the inbox.
Rule 1 — Spread mailboxes across domains
Inbox providers judge the domain, not just the mailbox. Twenty-five mailboxes on one domain share one reputation — if it gets flagged, all twenty-five die together. The right setup is 2–3 mailboxes per domain (so 25 mailboxes ≈ 10 domains). Oppora warns you at launch if too many mailboxes share a domain.
Rule 2 — Warm up before you send
A brand-new domain or mailbox must be warmed before real campaigns: minimum 14 days, up to 45 for a completely new domain. Keep warmup running even after campaigns start.
Rule 3 — Keep volume modest per mailbox
30–50 emails per mailbox per day is the sweet spot. Scale by adding mailboxes and domains — never by pushing one mailbox harder.
Rule 4 — Clean lists win
Verified emails, real personalization, an unsubscribe option, and no spammy wording (“free!!!”, “act now”) keep reply rates up and complaints down.
Rule 5 — Using tracking or unsubscribe? Set up a custom tracking domain
Open tracking, click tracking, and unsubscribe links all place a small web address inside your emails. Without setup, that address is a shared domain used by many senders — and spam filters notice the mismatch with your sending domain. A custom tracking domain (for example, track.yourcompany.com — one per sending domain, set up once) makes those links match your domain. Full walkthrough: Set up a custom tracking domain in the Email Campaign Management category.
The honest math on sending speed
Each mailbox sends one email, then rests for its own random gap (2–4 minutes by default) before the next — while one rests, another sends. The campaign moves fast overall while every individual mailbox looks calm and human.
What the warnings mean
FAQs
Q1: Why is my campaign sending “slowly”?
It’s pacing on purpose. Speed = number of mailboxes × their daily limits, spread across your sending window. Want more volume? Add more warmed mailboxes on more domains — don’t shrink the rest gaps; they’re what keeps you out of spam.
Q2: Why did sending stop and then continue by itself?
Usually a mailbox hit its daily limit or its provider asked for a short break. The engine rotates to other mailboxes and resumes automatically — nothing to do.
Q3: Can I raise a mailbox’s bounce-pause threshold?
Yes — it’s per-mailbox: how many bounces plus rejections per day it tolerates (default 20) and what failure percentage (default 15%, applied once the mailbox has sent 100+ that day). Both are adjustable in mailbox settings, but raising them trades safety for volume.
Q4: Do these rules apply to LinkedIn too?
The spirit does — human pacing and daily caps — and LinkedIn Automation enforces its own throttling. The domain and warmup rules are email-specific.
Conclusion
Follow the five rules and deliverability stops being a mystery: spread domains, warm up first, keep per-mailbox volume modest, send to clean lists, and brand your tracking links. Scale comes from adding calm mailboxes — never from rushing one.
