TL; DR / Ngaahi Meʻa Mahuʻinga

• ʻOku faʻa tupu ʻa e ngaahi hala ʻa e OTP mei he vave ʻo e reends, greylisting, mo e sender throttles.
• Te ke lava ʻo fakaʻaongaʻi ha tuʻunga vilo nounou; Toki vilo pe hili hono toe ʻave totonu ʻo e Windows.
• Fakaʻuhingaʻi ʻa e ngaahi tuʻunga mahino (per-sender failures, TTFOM) pea lekooti fefeka.
• Muimuiʻi ʻa e ola lelei ʻo e OTP, TTFOM p50/p90, lau ʻo e toe feinga, mo e vave ʻo e fetongi.
• Fakaʻehiʻehi mei he fuʻu fetongi; ʻoku ne maumauʻi ʻa e ongoongo mo puputuʻu ʻa e kau fakaʻaongaʻi.

Ngaahi Bottlenecks ʻi he Feituʻu

ʻIloʻi ʻa e feituʻu ʻoku fihia ai ʻa e OTP—ngaahi fehalaaki ʻi he tafaʻaki ʻo e kasitoma, fakangatangata ʻo e rate, pe greylisting—kimuʻa pea ke toki ala ki he domains.

ʻI heʻene vakai ki ai, ʻoku ngali maʻamaʻa. Ko hono moʻoni, ʻoku ʻi ai ha ngaahi fakamoʻoni makehe ʻo e mole ʻa e OTP. Kamata ʻaki ha mape vave ʻo e fehalaaki:

• Client/UI: hala ʻa e tuʻasila naʻe fakapipiki, ʻikai fakafoʻou ʻa e puha melino, pe ko ha vakai ʻoku siviʻi ki he fakamatala pe ʻoku taʻofi ʻa e ngaahi ʻata.
• SMTP/provider: greylisting ʻi he tafaʻaki ʻo e tokotaha ʻoku ne ʻomai, IP pe ʻa e tokotaha ʻoku ne ʻoatu ʻa e throttling, pe tuʻu fakataimi ʻi he laine.
• Taimi ʻo e netiueka *: tumutumu ʻo e ngaahi matapa ʻo e ngaahi meʻa lalahi, hala ʻoku ʻikai potupotutatau, mo e ngaahi fepaki ʻoku ne fakatoloi ʻa e meili ʻoku ʻikai mahuʻinga.

Fakaʻaongaʻi ʻa e ngaahi sivi vave:

• TTFOM (time-to-first-OTP message). Track p50 mo e p90.
• OTP Success Rate ki he tokotaha ʻoku ne ʻoatu (ko e saiti/app ʻoku tuku atu ʻa e ngaahi kouti ʻoku ne ʻoatu).
• Toe ʻAve ʻa e Window Adherence: ʻOku tuʻo fiha nai hono lomiʻi vave ʻe he kau fakaʻaongaʻi ʻa e toe ʻave?

ʻOku faingofua pe ʻa e ola: ʻoua naʻa ke vilo ʻa e ngaahi domain kae ʻoua kuo ke ʻiloʻi ʻa e meʻa ʻoku ʻikai lava. ʻOku taʻofi ʻe ha ʻaotita miniti ʻe taha heni ha ngaahi houa lahi ki mui.

Fakaʻapaʻapaʻi ʻa e Toe ʻAve ʻa e Windows

ʻOku faʻa kovi ange ʻa e malava ke ʻoatu ʻa e meʻafana—taimi hoʻo feinga hoko.

Ko hono moʻoni, ʻoku lahi ʻa e ngaahi polokalama OTP ʻoku fakataumuʻa ke tuai ʻa e toutou ʻave. Kapau ʻe toe feinga vave ʻa e kau fakaʻaongaʻi, ʻe kamata leva ʻa e ngaahi maluʻi ʻo e fakangatangata pea ʻoku toʻo ʻa e fakamuʻomuʻa ʻo e popoaki ko ʻeni—pe toʻo. Fakaʻaongaʻi ʻa e ngaahi matapa sioʻata pragmatic:

• ʻAhiʻahiʻi pe ʻa e 2 hili ha sekoni ʻe 30-90 mei he ʻuluaki feinga.
• ʻAhiʻahiʻi ʻa e 3 hili ha toe miniti ʻe 2–3.
• Fintech ʻoku tuʻu fakatuʻutamaki * ʻOku ʻaonga he taimi ʻe niʻihi ʻa e tafe mai ʻi he tatali ʻo aʻu ki he miniti ʻe nima kimuʻa pea fakalalahi ʻa e taf

Fokotuʻutuʻu ha tatau ʻoku ne fakanonga, kae ʻikai fakaʻita: "Kuo mau fehiʻa ʻi he kouti ko ʻeni. Toe vakaiʻi ʻi ha sekoni nai ʻe 60." Lekooti ʻa e toe ʻave kotoa pe ʻaki ʻa e timestamp, ʻome, domain ʻoku ngaue, mo e ola. ʻOku fakaleleiʻi ʻe he meʻa ni ha konga fakaʻohovale ʻo e ngaahi palopalema ʻo e "tufaki".

Fakaʻaongaʻi ha kiʻi tuʻunga fili siʻisiʻi; vilo pe ʻi he taimi ʻoku talamai ai ʻe he ngaahi fakaʻilonga.

ʻOku totonu ke ongoʻi taʻeoli mo mahino ʻa e fetongitongi ko ʻeni. Ko ha tuʻunga siʻisiʻi ʻeni te ke lava ʻo akoʻi ki hoʻo timi:

5. Vilo pe ʻa e tuʻasila meili fakataimi/domain ʻi he taimi ʻoku talamai ai ʻoku totonu ke ke maʻu.

Ngaahi tuʻunga ʻoku ne fakatonuhiaʻi ʻa e fetongitongi ʻo ha tuʻasila meili fakataimi

Ko e meʻa fakaʻohovale, he ʻikai tokoni ha toe domain ʻe hongofulu ma ua kapau ʻoku nau "longoaʻa" kotoa. Fokotuʻu ha vai kaukau kuo fokotuʻutuʻu:

• Ngaahi tuʻutuʻuni ki he maloloo: tuku ke mokomoko ha domain ʻi he taimi ʻoku holoki ai ʻene meʻatokoni; Tokanga ki he fakaakeake kimuʻa pea ke toe fakahu ia.
• Metadata ʻi he tafaʻaki takitaha: taʻu motuʻa, maaka moʻui lelei ʻi loto, mo e ngaahi lavameʻa fakamuimuitaha ʻa e tokotaha naʻa ne ʻomai.

Ngaahi meʻafua ʻoku ne fakamoʻoniʻi ʻoku ngaue ʻa e vilo

Kapau ʻoku ʻikai te ke fuatautau, ko e vilo ko ha fakakaukau pe ia.

ʻAnalaiso ʻo fakatatau ki he tokotaha naʻa ne ʻomai, domain, fonua/ISP (kapau ʻoku maʻu), mo e taimi ʻo e ʻaho. ʻI hono fakahoko, fakafehoanaki ha kulupu ʻoku nau tatali ʻi ha matapa sioʻata ʻe ua kimuʻa pea toki vilo mo ha variant ʻoku vilo hili ʻa e ʻuluaki taʻelavameʻa. ʻI he palanisi, ʻoku taʻofi ʻe he puleʻi ʻa e churn ʻoku ʻikai fie maʻu; ʻOku fakahaofi ʻe he variant ʻa e ngaahi keisi ʻi he tafaʻaki lolotonga ʻa e tuai ʻa e tokotaha ʻoku nau ʻomai. ʻE fili hoʻo ngaahi mataʻifika.
