Titan Email Going to Spam? Fix DNS, SMTP and Warm-Up

Titan Email deliverability checks for spam folder fixes

Titan Email going to spam usually means one of five checks is failing: SPF, DKIM, DMARC, authenticated SMTP, or sending behaviour. Keep sending while one fails and mailbox providers can reinforce a bad pattern. This guide gives the exact Titan settings, DNS checks, warm-up rules, and verification steps.

If you are connecting Titan to a warm-up tool, use the Titan Email warm-up guide after the DNS checks below. If the problem is not Titan-specific, compare this with the broader cold emails going to spam checklist.

Why is Titan Email going to spam?

Spam placement is rarely one setting. It is usually several small failures at once.

For Titan Email, start with the signals mailbox providers can check before a human reads the message. They look for authorised sending servers, domain signatures, DMARC alignment, recipient engagement, and complaints.

Use this table before changing templates or buying another tool.

Spam placement worsens after a jumpSudden sending patternCompare yesterday’s sent countStep down volume for several days
Yahoo is worse than GmailComplaint or alignment issueCheck Yahoo sender requirementsPass SPF, DKIM, DMARC and keep complaints under 0.3%

Do not skip authentication. Warm-up cannot rescue mail that fails sender authentication.

What numbers should you check first?

Check these settings before editing copy. Some are provider rules. Others are typical safe operating ranges for cold outreach.

Google publishes its current rules in its Email sender guidelines. Yahoo lists sender requirements in Yahoo Sender Best Practices. SPF’s 10-lookup limit comes from RFC 7208.

How do you fix authentication?

Authentication is the fastest place to win. It is also the easiest place to create a hidden failure.

1. Fix SPF

SPF tells receiving providers which servers may send mail for your domain.

Open DNS for the domain in your hosting or DNS provider. Look for a TXT record at the root domain. Your DNS panel may show it as @, blank, or the domain name.

You should have one SPF record. It starts with:

v=spf1

If you see two TXT records that both start with v=spf1, merge them. Do not leave both. SPF evaluators expect one policy.

For Titan, copy the current SPF include or value from Titan or your hosting reseller. Do not guess it from an old article. Titan is often sold through hosting partners, and control panels can differ.

If you also send through a cold email tool, CRM, newsletter platform, or SMTP relay, include those senders in the same SPF record. Then check the result with the free SPF checker.

Keep the total SPF evaluation under 10 DNS lookups. If you exceed that, SPF can fail even when the record looks correct.

2. Fix DKIM

DKIM signs mail with a domain key. It proves the message was authorised by the domain and was not changed after sending.

In Titan or your reseller control panel, find the DKIM section for the mailbox domain. Enable DKIM, then copy the exact selector and DNS value shown there.

A DKIM record normally uses a host like:

selector._domainkey.yourdomain.com

The selector is not universal. It may differ by provider, reseller, or setup date. Use the one Titan shows.

After publishing the record, wait for DNS to propagate. Then check the selector with the free DKIM checker. Also send a message from Titan to Gmail and open More → Show original. Look for DKIM: PASS.

If DKIM fails, check three things:

Do not scale sending until DKIM passes.

3. Fix DMARC

DMARC tells providers what to do when SPF or DKIM fail alignment. It also helps you see whether your domain authenticates correctly.

Start with this record while fixing Titan deliverability:

v=DMARC1; p=none;

Publish it as a TXT record at:

_dmarc.yourdomain.com

You can add a reporting address if you monitor reports:

v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com;

DMARC passes when SPF or DKIM passes and aligns with the visible From domain. For most Titan setups, DKIM alignment is the cleaner path because it ties the signature to your domain.

Check the record with the free DMARC checker. Then send a real test and inspect the authentication result in the receiving mailbox.

Do not move straight to p=reject while fixing spam placement. Start with p=none, verify alignment, then harden the policy later if you need it.

Are your Titan settings correct?

Wrong SMTP settings can create failed sends, relay errors, or unusual login patterns. Those problems can look like deliverability issues.

Titan’s standard settings are:

PurposeHostPortSecurityPassword
IMAP receiveimap.titan.email993SSLMailbox password
SMTP sendsmtp.titan.email465SSLMailbox password
EU IMAPimap0101.titan.email993SSLMailbox password
EU SMTPsmtp0101.titan.email465SSLMailbox password

If two-factor authentication is enabled, use an app password. Titan also requires third-party app access before external IMAP and SMTP tools can connect.

Use the current Titan instructions for your account type. Titan’s official help article on configuring Titan in other apps is the primary source for these settings.

When you connect Titan to BobWork Email Warm-up, use Other IMAP + SMTP. Enter the IMAP host, SMTP host, full email address, and mailbox password or app password. Each mailbox gets the same login test as a single connection.

A failed connection is not a spam-folder problem. Fix access first.

What sending signals cause spam?

After authentication passes, inspect what you send and who receives it.

Spam filters use engagement and complaints. A perfectly authenticated email can still go to spam if recipients ignore, delete, or mark it as spam.

Cut risky content

For a test, send a plain text email with no links, no images, and no tracking pixel. Keep it short. Use a normal first-name greeting and a clear reason for the message.

If the plain test reaches Inbox but your campaign lands in Spam, the issue is probably content or tracking.

Common cold email risks include:

Use one clear link at most. For early tests, use no link. Ask for a reply instead.

Clean the list

Bad lists create bounces and complaints. Those signals can damage a Titan mailbox faster than warm-up can repair it.

Do not use purchased or scraped lists without verification and targeting. Remove role accounts where appropriate. Suppress unsubscribes forever. Stop sending to contacts who bounce.

If you run cold email, use one-click unsubscribe for bulk-like campaigns. Yahoo requires one-click unsubscribe for bulk senders, and Google also expects easy unsubscribe for qualifying senders. RFC 8058 defines the one-click List-Unsubscribe mechanism.

Lower volume

Sudden jumps are a common reason Titan mail starts going to spam.

If you sent 5 messages yesterday and 150 today, that is not a normal mailbox pattern. Step down. Keep new or recently fixed mailboxes at low daily volume until inbox placement stabilises.

For cold outreach, a typical safer range is 30–50 real cold emails per mailbox per day. Add mailboxes and domains instead of forcing one Titan inbox to do all the work.

For pacing examples, use the warm-up schedule generator or read the email warm-up schedule guide.

When should you use warm-up?

Warm-up is useful when your domain and mailbox need positive sending history. It is not a substitute for correct DNS, consent, list quality, or relevant email.

Use warm-up when:

Do not use warm-up as the main fix when:

BobWork Email Warm-up can help once the setup is clean. It starts at 3 emails per day, adds 2 per day, and caps at 30 per day by default. Weekends run at 30%. Sends are spread across 09:00–18:00 in the mailbox’s time zone.

The service uses a shared warm-up network by default, or a private pool per account if you prefer. Warm-up messages are plain-text office notes. About 40% get a reply, and threads end after 3 messages.

If a warm-up email lands in Spam, the engine moves only its own warm-up mail to Inbox, marks it read, labels it “Warm-up”, and archives it after 24 hours. Real mail is never read, moved, or answered.

Use 7 days for an existing domain. Use 2–3 weeks for a new domain. During campaigns, keep warm-up running at about 10–15 per day and keep real outreach modest.

How do you prove it worked?

Start with the fastest checks. Do not rewrite the whole campaign before you know whether authentication passes.

1Send a Titan test email to GmailOpen Gmail → More → Show original
2Check SPF resultLook for SPF: PASS
3Check DKIM resultLook for DKIM: PASS

10Use an app password if 2FA is onLogin succeeds without disabling 2FA
11Send a plain text test with no linksCompare inbox placement with campaign copy
12Pause high-volume sending for a few daysSpam placement stops worsening
13Start warm-up if DNS passesMailbox receives and sends gradual warm-up mail
14Resume cold email slowlyStay near 30–50/day/mailbox once stable

If DNS changed recently, wait for propagation before judging. Some records appear quickly. Others take longer depending on TTL and resolver caching.

Test with receiving mailboxes, not only DNS screens. Send to Gmail, Yahoo, and a Microsoft mailbox if you can. Use the same Titan mailbox and From address you use for real outreach.

In Gmail, open the message, click the three-dot menu, then Show original. Confirm SPF, DKIM, and DMARC pass. If one fails, fix that before judging inbox placement.

In Yahoo, confirm the message reaches Inbox and not Spam. Yahoo requires SPF and DKIM, DMARC at least p=none, alignment, one-click unsubscribe for bulk, and spam rate under 0.3%.

For Microsoft consumer mailboxes, Microsoft has requirements for domains sending over 5,000 emails per day. Those include SPF pass, DKIM pass, and DMARC at least p=none with alignment. If you are nowhere near that volume, the same authentication checks still help.

Next, test the exact campaign version. Send one plain text control and one campaign email. If the control inboxes but the campaign spams, DNS is not the main issue. Review links, tracking, formatting, subject line, and targeting.

Watch live sending behaviour for at least 7 days. You want stable inbox placement, low bounces, replies, and no complaint spike. If warm-up is running, check the 7-day spam rate instead of one landing.

In BobWork, a mailbox is ready for outbound after 7+ days warming, a 7-day spam rate of 10% or lower, and at least 30 warm-up emails received. Treat that as a readiness gate, not a guarantee of inbox placement.

Keep the fix in place. Do not pass one test and immediately jump volume. Titan mailboxes behave like normal business inboxes when the pattern stays normal. Change one thing at a time, measure the result, and add mailboxes instead of forcing one mailbox to carry the campaign.

You can start with the free DNS tools, then connect Titan through the free warm-up tool when SPF, DKIM, and DMARC pass. Use the Titan provider guide for the exact connection flow, and keep the SPF, DKIM, and DMARC checkers open while you test.

What else do people ask?

Why is my Titan Email going to spam?

The usual causes are failing SPF, DKIM or DMARC, a new sending domain, high bounce rates, spam complaints, link-heavy cold email, or sudden volume. Check authentication first, then content, list quality, and sending pace.

What SPF record should I use for Titan Email?

Use the current SPF value shown by Titan or your hosting reseller. Publish only one SPF TXT record at the root domain. If you also send through other tools, merge their includes into that one record and keep SPF under 10 DNS lookups.

Does Titan Email need DKIM?

Yes. DKIM helps mailbox providers verify that your domain authorised the message. Enable DKIM in Titan or your reseller panel, then verify the selector with a DKIM checker and a Gmail Show original test.

What DMARC policy should Titan Email use?

Start with p=none while you test. Publish the record at _dmarc.yourdomain.com. After SPF and DKIM pass consistently, you can move to quarantine or reject if that suits your domain policy.

Can warm-up fix Titan emails going to spam?

Warm-up can help when authentication passes and the domain or mailbox has little sending history. It will not fix broken SPF, DKIM, DMARC, a poor list, high complaints, high bounces, misleading content, or a blocked mailbox.

What Titan SMTP settings should I check?

Titan’s standard SMTP setting is smtp.titan.email on port 465 with SSL. EU accounts may use smtp0101.titan.email. If the account has 2FA, use an app password. Third-party app access must be enabled.

How long does Titan warm-up take?

For an existing healthy domain, plan at least 7 days. For a new domain, plan 2–3 weeks before cold outreach. Once stable, keep outreach modest, typically 30–50 real cold emails per mailbox per day.
